Implementing a bot for sc2 collectables minigame

[RickFqt]

When this PR is complete, it should implement a bot that can be trained and used to solve the starcraft2 collectables minigame.

TODO list:

• Fix linter checks
• Implement the persistance class
• Fix the method choose_action from agent_base and model_base
• Fix existing tests

I had to adapt the Persistence class a little bit for this issue, and i think the Persistence class in v2 should also suffer these changes. Basically, it now receives a object_to_save and stores/loads the data onto it instead of using the class itself like before.
