WIP - feat: Support hashed datum options for inputs and outputs

[AndrewWestberg]

This PR has a basic framework for creating an output that only has a datum hash and not inline datum. However, it's stuck in that I can't seem to reference source fields.

The other issue is in Pallas: txpipe/pallas#711

The test transaction that gets built has no script datum hash value because there are no redeemers. This is an incorrect behavior of pallas.

@scarmuega I don't understand how the system works for referencing inputs from outputs. I get an error currently when I attempt to do this.
