Consider Deterministically Encoded CBOR

[cyberphone]

Deterministically Encoded CBOR which is slated for becoming an IETF standard, opens new possibilities for signature schemes. It seems ideally fitted for new designs, like the EU ID Wallet.

The primary objectives with Deterministically Encoded CBOR are:
🔸 Strict (non-ambiguous) encoding of data items.
🔸 The ability to use "raw" CBOR as input to signature/hash functions.
