Add Fake operations for anoma-resource-commitment and anoma-resource-nullifier

[mariari]

I want to run things in the repl to get a good feeling for the shape of data as I go, however I can't do this if data just fails to run.

myResourceCommitment : Nat := base-commitment myResource;

myResourceEphNullifier : Nat := base-nullifier myResourceEph;

Swap> myResourceCommitment
/repl:1:1: error:
evaluation error: unsupported builtin operation: OpAnomaResourceCommitment: anoma-resource-commitment ?
Swap> myResourceEphNullifier
/repl:1:1: error:
evaluation error: unsupported builtin operation: OpAnomaResourceNullifier: anoma-resource-nullifier ?

this makes me sad as when trying to look at composite data structures over this I can't just evaluate terms and figure out how examples work easily.
