Single-Signer (plain old Schnorr, sans-multisig) signature verification Returns: Ok(Signature) on success In: sig: The signature msg: the message to verify pubnonce: if Some(PublicKey) overrides the public nonce used to calculate e pubkey: the public key pubkey_total: The total of all public keys (for the message in e) is_partial: whether this is a partial sig, or a fully-combined sig
