v1.3

• Added unit tests for all files in the package
  • The tests mostly revolve around ensuring correct setup of the config and making sure training/saving/loading/evaluating all models and (compatible) datasets with all (compatible) metrics for regression/classification works
• Added/fixed code for simple regression datasets and models (regression wasn't used / tested too much before)
• Added several util functions (mostly used only in unit testing for now)
• Stricter and better asserts in config.py
• Renamed datasets.py to datasets_dl.py and created datasets.py only for loading different datasets (for consistency with models.py and models_dl.py
• Added a pre-push hook for automatically running tests before each hook (pre-commit would've been too frequent and slowed down development)
• Minor code cleanup + docstring improvements + bug fixes + Readme updates
