Implement a DLEq library While Serai only needs the simple DLEq which was already present under monero, this migrates the implementation of the cross-group DLEq I maintain into Serai. This was to have full access to the ecosystem of libraries built under Serai while also ensuring support for it. The cross_group curve, which is extremely experimental, is feature flagged off. So is the built in serialization functionality, as this should be possible to make nostd once const generics are full featured, yet the implemented serialization adds the additional barrier of std::io.

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

Implement variable-sized windows into multiexp Closes https://github.com/serai-dex/serai/issues/17 by using the PrimeFieldBits API to do so. Should greatly speed up small batches, along with batches in the hundreds. Saves almost a full second on the cross-group DLEq proof.

Correct std feature-flagging If a crate has std set, it should enable std for all dependencies in order to let them properly select which algorithms to use. Some crates fallback to slower/worse algorithms on no-std. Also more aggressively sets default-features = false leading to a *10%* reduction in the amount of crates coordinator builds.

Update the DLEq proof for any amount of generators The two-generator limit wasn't required nor beneficial. This does theoretically optimize FROST, yet not for any current constructions. A follow up proof which would optimize current constructions has been noted in #38. Adds explicit no_std support to the core DLEq proof. Closes #34.

\#242 Expand usage of black_box/zeroize This commit greatly expands the usage of black_box/zeroize on bits, as it originally should have. It is likely overkill, leading to less efficient code generation, yet does its best to be comprehensive where comprehensiveness is extremely annoying to achieve. In the future, this usage of black_box may be desirable to move to its own crate. Credit to @AaronFeickert for identifying the original commit was incomplete.
