WitnessRules from JSON not implemented

[Devel484]

Recently Ghostmarktet started to use Witness Rules, due to that the python SDK has issues to parse a TX from JSON. The required code is not implemented and not integrated in the workflow.

Code to replicate:

tx = await rpc.get_transaction("5f0259d536ce6791422fbdbe55ce6231bde02d6b75699c260e45c02dbc4acfc2")
data = tx.to_json()
print(tx.to_array().hex())
