Pre commit

See merge request !14

To enable the pre-commit checks first run pip -Ur requierements.txt to install pre-commit. Next run pre-commit install to install the hook in your .git/hooks folder. Running pre-commit will now run prospector on all new or modified files in the backend/ directory (see pre-commit-scripts/prospector.sh for the arguments that are used). If you get an error saying prospector not found or smth. make sure you have the venvv activated or prospector installed globally.
