Using hydra-core for configuration?

[erenovic]

Hello @AlmondGod , thanks for the great repository! I love the simple structure and learning more about world models through this repository. I want to help with development of this repository and I thought adopting hydra-core for configurations could be a nice structural improvement. If everyone else is supportive of this idea, I can help with changing the configurations to adopt hydra-core

this would be great, would appreciate if you create a PR for this!
