FROST(secp256k1, SHA-256) Taproot - A Schnorr signature scheme over secp256k1 that supports
FROST threshold signatures compatible with BIP-340 (Schnorr) and BIP-341 (Taproot).
This module provides a complete implementation of the FROST ciphersuite for the secp256k1
group with SHA-256 as the hash function, with modifications for Taproot compatibility:
BIP-340 tagged hashes for challenge computation
BIP-341 Taproot key tweaking
x-only public key format (32 bytes)
64-byte signature serialization (x-only R point + z)
EvenY trait for ensuring public keys have even Y coordinate
