Use `hydra` to handle configs

[Pale-Blue-Dot-97]

Is your feature request related to a problem? Please describe. Performing hyper-parameter sweeps with the current config handling will be a bit messy. How configs are handled across minerva is also inefficient, with configs being parsed around frequently.

Describe the solution you'd like Adopt hydra for config handling across minerva.

Describe alternatives you've considered Continue using the current config structure.
