New release: cardano-signer 1.12.0

New with v1.12.0:
- The output via `--json-extended` is now showing more details about the address (hex, type, network)
- The help description can now be displayed for each sub command like: `cardano-signer sign --cip8 --help`
- Addresses provided via the `--address` parameter can now be a bech-address, hex-string or the path to a file containing the bech-address (typical mywallet.addr) files
- Completely reworked CIP-8/CIP-30 code. Flags `--cip8` & `--cip30` will currently do the same, because CIP-30 uses CIP-8 signing.
- Signing a payload now generates a full COSE_Sign1 signature together with the COSE_Key publicKey
- The payload can be set to hashed via the new flag `--hashed`
- The payload can be excluded from the COSE_Sign1 signature with the new flag `--nopayload`
- The signing address will be automatically checked against the publicKey (signing and verification)
- Extended data structure check of the given COSE_Sign1 & COSE_Key
- Verification can be done against the COSE_Sign1 & COSE_Key, and optionally also against a given payload and address
- The output via `--json-extended` shows additional information if the payload is hashed, address infos, etc.
