Add support for CKTap protocol

[notmandatory]

Describe the enhancement

Add CKTap protocol support for BDK based wallets used on Android or iOS devices.

Use case

Supporting the CKTap protocol would allow a BDK based mobile wallet to:

1. Setup, view balance and transactions, and sweep funds from a SATSCARD card via an NFC tap.
2. Setup, view balance and transactions, and sign or co-sign transactions using a TAPSIGNER card via an NFC tap.

Additional context

Some functionality may make sense to move to the BDK rust library or a new rust crate, such as the CBOR message structures.

This enhancement was suggested by @nvk.

I found this rust lib for desktop testing: https://crates.io/crates/pcsc
and this lib for cbor encoding: https://crates.io/crates/ciborium
