The FROST RFC (https://datatracker.ietf.org/doc/rfc9591/) has test vectors that can be used to validate an implementation (section E.5. for secp256k1, SHA-256). We should add tests that see if/where we fail to validate. Since we use Taproot style challenge hashing, we know for certain that there will be discrepancies; likewise, v2 will not match unless we use a degenerate case.
