Pip freeze

An idea how to fix requirements, as a ground for discussions. The idea is to avoid situations like this: #463

• have a defined environment (Docker) to resolve the dependencies and create _requirements_freeze.txt

docker build -f Dockerfile.pipfreeze --progress=plain -t pipfreeze .
docker run -v ./requirements/:/app/output -t pipfreeze

• use _requirements_freeze.txt for the stable installation

If one forgets to update _freeze.txt, this would be the error:

ERROR: Cannot install alphadia[stable]==1.9.3.dev2 because these package versions have conflicting dependencies.

The conflict is caused by:
alphadia[stable] 1.9.3.dev2 depends on ruff==0.9.1; extra == "stable"
alphadia[stable] 1.9.3.dev2 depends on ruff==0.9.2; extra == "stable"

could add a test that checks that prevents that error by checking that all versions defined in requirements.txt are actually exactly the same as in _requirements_freeze.txt (similiar to what we already have)
