Mirror the public Nunchuk CKTapCard interface in Flutter #22
Description
A follow on from this: #23
NFC functions, these need to be ran within TapProtocolThread:
- CKTapCard::Send(msg) - Consider allowing the user to provide CBOR data or investigate a way to reconstruct a nlohmann::json (looks complicated)
- CKTapCard::SendAuth(msg, cvc) - See above
- CKTapCard::Status() - Consider returning a reconstructed Satscard/Tapsigner instead of serializing the response struct
- CKTapCard::NFC() - Just need to return the converted string
- CKTapCard::CertificateCheck(pubKey) - Return either a bool or a reconstructed Satscard/Tapsigner
- CKTapCard::New(chain_cde, cvc, slot) - Not entirely sure the value of this compared to Satscard::New. Could just return a serialized NewResponse
- CKTapCard::Sign(digest, cvc, slot, subPath) - Should be simple to implement
