- add pre-commit and pre-merge hooks:
+ run `poetry run nox -s pre-commit` on staged *.py files
+ run common pre-commit hooks for validations that could not be
achieved with tools in the develop environment so easily
+ run `poetry run nox -s pre-merge` before merges and pushes
- implement the "pre-commit" and "pre-merge" sessions in nox
+ include a little hack to deal with the positional arguments
passed by the pre-commit framework
- provide more documentation on the nox sessions
