Apply parameters on plutus scripts

[mpizenberg]

Many plutus scripts are compiled first without all its parameters fixed. Then we can "apply parameters" to them to get their final form before using the scripts.

On most offchain frameworks, there is a function to do this.

• elm-cardano: https://github.com/elm-cardano/elm-cardano/blob/97fa1f56da482ae7c6e580677f6807aee6db3fb9/src/Cardano/Uplc.elm#L142

It would be very useful if we had the capabilities to do that with pycardano. I’ve seen that opshin can do it, but opshin isn’t maintained up-to-date with the chain and doesn’t support PlutusV3 it seems.

In case useful, the next version of Aiken will include this PR, which enables usage of aiken blueprint apply --in some/plutus.json ... outside of an aiken project. This is pretty convenient to call it with subprocess.run() in python with just the path to a blueprint json file instead of needing to be inside an aiken project directory. aiken-lang/aiken#1163
