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

Update to ethers 1.0
Removes rust_decimal as a depend, which added borsh and multiple other misc
packages in the previous commit.

Create a dedicated crate for the DKG (#141)
* Add dkg crate

* Remove F_len and G_len

They're generally no longer used.

* Replace hash_to_vec with a provided method around associated type H: Digest

Part of trying to minimize this trait so it can be moved elsewhere. Vec, 
which isn't std, may have been a blocker.

* Encrypt secret shares within the FROST library

Reduces requirements on callers in order to be correct.

* Update usage of Zeroize within FROST

* Inline functions in key_gen

There was no reason to have them separated as they were. sign probably 
has the same statement available, yet that isn't the focus right now.

* Add a ciphersuite package which provides hash_to_F

* Set the Ciphersuite version to something valid

* Have ed448 export Scalar/FieldElement/Point at the top level

* Move FROST over to Ciphersuite

* Correct usage of ff in ciphersuite

* Correct documentation handling

* Move Schnorr signatures to their own crate

* Remove unused feature from schnorr

* Fix Schnorr tests

* Split DKG into a separate crate

* Add serialize to Commitments and SecretShare

Helper for buf = vec![]; .write(buf).unwrap(); buf

* Move FROST over to the new dkg crate

* Update Monero lib to latest FROST

* Correct ethereum's usage of features

* Add serialize to GeneratorProof

* Add serialize helper function to FROST

* Rename AddendumSerialize to WriteAddendum

* Update processor

* Slight fix to processor

Fill out Cargo.tomls
Updated missing fields/sections, even if some won't be used, to 
standardize.

Also made FROST tests feature-gated.

Update dependencies
ethers previously used a git spec due to depending on not-yet-published 
updates. Now that they've been released, a properly published version is 
used.

set up CI (#45)
* begin to setup ci

* attempt to fix build

* fix paths in build script

* fix

* satisfy clippy

* update fmt check to use nightly

* use nightly for build

* fmt

* fix fmt install

* update test script

* try to fix fmt

* merge w develop

* maybe fix build script

* install wasm toolchain

* install solc-select, use stable rust to build

* Correct clippy warnings

Currently intended to be done with:
cargo clippy --features "recommended merlin batch serialize experimental 
ed25519 ristretto p256 secp256k1 multisig" -- -A clippy::type_complexity 
-A dead_code

* Remove try-runtime

I tried to get this to work for an hour. I have no idea why it doesn't, 
yet it doesn't.

* Rewrite workflow

Splits tasks into a more modular structure. Also uses 
actions-rs/toolchain.

* Add a cache

* Immediately try building ETH/Monero while this is fixed

Adds solc-select use.

* Revert selective advance building of ETH/XMR

ETH builds now, so it hopefully should work now.

Also moves from on push to on push to develop.

* Install Monero runtime dependencies

Specify missing Rust toolchain setting.

* Correct multi-line commands

* Fix multi-line commands again

Cache Ethereum artifacts.

* Add Foundry

* Move Clippy under build

* Minimal rustup

Adds wasm Clippy. Puts Clippy before build.

* Use nightly clippy

* Remove old clippy call from under build

* Have the Monero build script support ARCH specification

Requirement for CI.

* Add WASM toolchain to tests

* Remove Ethereum cache which did not work as needed

* Remove extraneous quotes which broke builds on Arch
