## Summary
This PR implements an "ActionPenalty" Reward class, that can be used for penalising an agent when it carries out an action other than DONOTHING.
The value for this can be configured within the scenario YAML file.
## Test process
I've written unit tests to check that the action penalty is correctly calculated and applied, another to check that the config is read correctly and loads into PrimaiteGymEnv correctly.
