Add support for --cddl-format option

The cli currently has an intermediate TxBody type that is serialised in an intermediate format which does not follow cardano-ledger's CDDL spec.
A flag was added to the cli allowing the CDDL serialisation of any relevant outputs. Eventually the cli's intermediate format will be deprecated.
