Double-check node handling of inline datum in inputs

[SebastienGllmt]

I really want to believe the node implementation doesn't match what the spec implies on handling of inline datums in inputs where you'd have to duplicate inline datums inside the witness set.

See add_reference_input and input_required_wits

Somebody mentioned to me that if they spend an inline datum and yet specify the datum of the input in their own transaction, they get a NonOutputSupplimentaryDatums error. I haven't verified this myself though
