64 switch to pyprojecttoml for dependencies

[plhrtr]

• Right now all versions are locked to the newest version available, so that future changes can't break our codebase, but I could also only lock the version of artist-csp
• I dont really know if it would be better to just fix the versions in the requirements.txt file, because pip install . also tries to build the app and this currently isn't configured. (The packages.find is there because it wont build with out it)
