Function bls12381_min_sig_verify

@param signature: A 48-bytes signature that is a point on the G1 subgroup. @param public_key: A 96-bytes public key that is a point on the G2 subgroup. @param msg: The message that we test the signature against.

If the signature is a valid signature of the message and public key according to BLS_SIG_BLS12381G1_XMD:SHA-256_SSWU_RO_NUL_, return true. Otherwise, return false.
