Adding GeCo to Carla

[GibbsG]

Hi,

This PR is for adding GeCo, a counterfactual model, to Carla Benchmark. I also added the test in test/test_cfmodel.py and also updated the experiments to include GeCo.

Please have a look!

Thanks!
Gibbs

Hi, thanks for submitting your PR.

Some comments on first glance:

• Could you add ".DS_Store" to the .gitignore, and remove those files from the PR?
• Did you follow this: https://carla-counterfactual-and-recourse-library.readthedocs.io/en/latest/installation.html#contributing? It seems there are some small problems with the formatting of the code. If there is anything unclear there please let us know, then we can add improvements.
• Also I think Julia needs to be added to the requirements. Could you tell which version you use? (and if there are also other important packages, with their version) I'll try to fix that for you then, because there are multiple files with requirements so that's always a bit confusing.

@GibbsG thanks for submitting your first PR! A great addition to also have some Julia based models included. See few comments below

Hi @JohanvandenHeuvel thanks for reviewing it. I think most of them are addressed. The packages for GeCo itself are located at this file: carla/recourse_methods/catalog/geco/library/GeCo.jl/Manifest.toml. To run Julia in Python, we need one additional package from here https://pyjulia.readthedocs.io/en/latest/installation.html.
