Cardano HW cli v1.10.0

Added:

• support for signing Alonzo-era txs 🎉
• support for the new CDDL-compliant tx format (use --cddl-format when building transactions with cardano-cli)

Deprecated (see README for details):

• cardano-cli's internal raw tx format (--tx-body-file) in favor of the new CDDL-compliant tx format (--tx-file)
• transaction sign call in favor of the transaction witness call

Fixed:

• Ledger no longer creates a staking witness for staking key registration certificate (consistently with Trezor)
• superfluous witness output files are reported as a warning, missing witness output files are reported as an error

Changed:

• upgraded Node.js to v14

Tested with Cardano Ledger App v4.0.0 and Trezor Firmware v2.5.0 or newer.
