Add method to add full datum to transaction in output_builder about cardano-multiplatform-lib HOT 2 OPEN

Hi!, I wrote a posible workaround in this issue:

Emurgo/cardano-serialization-lib#443 (comment)

from cardano-multiplatform-lib.

Isn't this already possible by calling add_plutus_datum in the TransactionWitnessSetBuilder ?, my project is one of those such cases in which the validator needs both the full current and the next datum values (to enforce state transition rules on the datum data).

I am looking to migrate to this library from the serialization lib, I was hoping this was already supported.

If I understand correctly, you must call with_data_hash on the TransactionOutputBuilder and then make sure to include the full datum on the witness set by calling add_plutus_datum in the TransactionWitnessSetBuilder.

This would emulate the tx-out-datum-value on the cardano cli.
