This PR is an initial attempt to add the following two novel recourse methods to the library, FARE and E-FARE [1]. Differently from other approaches, FARE couples a reinforcement learning agent and a discrete search procedure, MCTS, to efficiently discover counterfactual interventions.
Currently, I have added FARE and a simple pytest to show its usage. Some class/function documentation is still missing, but I would like to start a discussion about what would be the best strategy to proceed.
This PR also adds as a dependency the sml-unitn/recourse-fare repository where the original code is located (in order to avoid bloating CARLA with additional files). Obviously, this can be changed.
