Introduces missing CLSAG checks. The only difference now should be the
additional rejection of torsioned points, which is relevant to
https://github.com/serai-dex/serai/issues/25. Considering this is only
currently used for FROST verification, this should be fine.
Closes https://github.com/serai-dex/serai/issues/19 by making it
irrelevant.
Increases priority of https://github.com/serai-dex/serai/issues/68, as
now it's used for the BP generators which are done at first-proof.
Also merges BP's stricter hash_to_point with the library's, since CLSAG
has the same bound.
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
Updates CLSAG signing as needed. Moves around Error types.
CLSAG multisig and the multisig feature is currently completely borked
because of this. The created TXs are accepted by Monero nodes.
