Enable static checks

[elvijs]

We should automatically run black, lint and isort on the code as well as the notebooks (see the suggestion below).

format_notebooks:
	jupytext --pipe 'isort - --treat-comment-as-code "# %%" --float-to-top' $(NOTEBOOK_PATH)/*.ipynb
	jupytext --sync --pipe black $(NOTEBOOK_PATH)/*.ipynb

This runs black and isort on the notebooks which is pretty cool
