Add IsEquivalentPubKeys, a helper method that reports whether two public keys are equivalent in their BIP340-serialized form. This ensures a canonical comparison by avoiding discrepancies caused by multiple encodings of the same elliptic curve point, since BIP340 serialization provides a unique byte representation.
