verify
verify (using blockchain compatible SHA256 and Schnorr) the provided data with the provided address (this wallet must have the private key for that address), or pass null to use the common identity. Use libnexa.verifySignedHashSchnorr or libnexa.verifySignedDataSchnorr if you need to verify a non-wallet signature with a public key. You may call verifySigForData instead as a shortcut if you have the data "preimage" not the hash and want to automatically use the standard cryptographic hash for this blockchain.
