Convert the FeaturedAddress tuple to a struct
Not only did we already have multiple booleans in it, yet it theoretically
could expand in the future. Not only is this more explicit, it actually cleans
some existing code.

    Remove Scanner::address

    It either needed to return an Option, panic on misconfiguration, or return a
    distinct Scanner type based on burning bug immunity to offer this API properly.
    Panicking wouldn't be proper, and the Option<Address> would've been... awkward.
    The new register_subaddress function, maintaining the needed functionality,
    also provides further clarity on the intended side effect of the previously
    present Scanner::address function.

    Add Substrate "assets" pallet

    While over-engineered for our purposes, it's still usable.

    Also cleans the runtime a bit.

    Remove the timestamp pallet

    It was needed for contracts, which has since been removed. We now no longer
    need it.

    Initial validator sets pallet (#187)

    * Initial work on a Validator Sets pallet

    * Update Validator Set docs per current discussions

    * Update validator-sets primitives and storage handling

    * Add validator set pallets to deny.toml

    * Remove Curve from primitives

    Since we aren't reusing keys across coins, there's no reason for it to be
    on-chain (as previously planned).

    * Update documentation on Validator Sets

    * Use Twox64Concat instead of Identity

    Ensures an even distribution of keys. While xxhash is breakable, these keys
    aren't manipulatable by users.

    * Add math ops on Amount and define a coin as 1e8

    * Add validator-sets to the runtime and remove contracts

    Also removes the randomness pallet which was only required by the contracts
    runtime.

    Does not remove the contracts folder yet so they can still be referred to while
    validator-sets is under development. Does remove them from Cargo.toml.

    * Add vote function to validator-sets

    * Remove contracts folder

    * Create an event for the Validator Sets pallet

    * Remove old contracts crates from deny.toml

    * Remove line from staking branch

    * Remove staking from runtime

    * Correct VS Config in runtime

    * cargo update

    * Resolve a few PR comments on terminology

    * Create a serai-primitives crate

    Move types such as Amount/Coin out of validator-sets. Will be expanded in the
    future.

    * Fixes for last commit

    * Don't reserve set 0

    * Further fixes

    * Add files meant for last commit

    * Remove Staking transfer

Support caching preprocesses in FROST (#190)
* Remove the explicit included participants from FROST

Now, whoever submits preprocesses becomes the signing set. Better separates
preprocess from sign, at the cost of slightly more annoying integrations
(Monero needs to now independently lagrange/offset its key images).

* Support caching preprocesses

Closes https://github.com/serai-dex/serai/issues/40.

I *could* have added a serialization trait to Algorithm and written a ton of
data to disk, while requiring Algorithm implementors also accept such work.
Instead, I moved preprocess to a seeded RNG (Chacha20) which should be as
secure as the regular RNG. Rebuilding from cache simply loads the previously
used Chacha seed, making the Algorithm oblivious to the fact it's being
rebuilt from a cache. This removes any requirements for it to be modified
while guaranteeing equivalency.

This builds on the last commit which delayed determining the signing set till
post-preprocess acquisition. Unfortunately, that commit did force preprocess
from ThresholdView to ThresholdKeys which had visible effects on Monero.

Serai will actually need delayed set determination for #163, and overall,
it remains better, hence it's inclusion.

* Document FROST preprocess caching

* Update ethereum to new FROST

* Fix bug in Monero offset calculation and update processor

Support handling addresses from other networks
A type alias of MoneroAddress is provided to abstract away the generic. 
To keep the rest of the library sane, MoneroAddress is used everywhere.

If someone wants to use this library with another coin, they *should* be 
able to parse a custom address and then recreate it as a Monero address. 
While that's annoying to them, better them than any person using this 
lib for Monero.

Closes #152.

Utilize zeroize (#76)
* Apply Zeroize to nonces used in Bulletproofs

Also makes bit decomposition constant time for a given amount of 
outputs.

* Fix nonce reuse for single-signer CLSAG

* Attach Zeroize to most structures in Monero, and ZOnDrop to anything with private data

* Zeroize private keys and nonces

* Merge prepare_outputs and prepare_transactions

* Ensure CLSAG is constant time

* Pass by borrow where needed, bug fixes

The past few commitments have been one in-progress chunk which I've 
broken up as best read.

* Add Zeroize to FROST structs

Still needs to zeroize internally, yet next step. Not quite as 
aggressive as Monero, partially due to the limitations of HashMaps, 
partially due to less concern about metadata, yet does still delete a 
few smaller items of metadata (group key, context string...).

* Remove Zeroize from most Monero multisig structs

These structs largely didn't have private data, just fields with private 
data, yet those fields implemented ZeroizeOnDrop making them already 
covered. While there is still traces of the transaction left in RAM, 
fully purging that was never the intent.

* Use Zeroize within dleq

bitvec doesn't offer Zeroize, so a manual zeroing has been implemented.

* Use Zeroize for random_nonce

It isn't perfect, due to the inability to zeroize the digest, and due to 
kp256 requiring a few transformations. It does the best it can though.

Does move the per-curve random_nonce to a provided one, which is allowed 
as of https://github.com/cfrg/draft-irtf-cfrg-frost/pull/231.

* Use Zeroize on FROST keygen/signing

* Zeroize constant time multiexp.

* Correct when FROST keygen zeroizes

* Move the FROST keys Arc into FrostKeys

Reduces amount of instances in memory.

* Manually implement Debug for FrostCore to not leak the secret share

* Misc bug fixes

* clippy + multiexp test bug fixes

* Correct FROST key gen share summation

It leaked our own share for ourself.

* Fix cross-group DLEq tests

While it was fine as-is, as it only had one variable length property, 
this is a bit more robust. Also binds the Curve ID, which should declare 
differently even for just different basepoints, and therefore adds two 
variable length properties (justifying the transcript).

Add a batch verifier to multiexp, along with constant time variants
Saves ~8% during FROST key gen, even with dropping a vartime for a 
constant time (as needed to be secure), as the new batch verifier is 
used where batch verification previously wasn't. The new multiexp API 
itself also offered a very slight performance boost, which may solely be 
a measurement error.

Handles most of https://github.com/serai-dex/serai/issues/10. The blame 
function isn't binary searched nor randomly sorted yet.

Honestly, the borrowed keys are frustrating, and this probably reduces

they enable full u16 indexing and should mildly improve the API.
