Simplify dependency management

[viperior]

I currently have requirements.in and requirements.txt files that are used in combination with pip and pip-tools to manage project dependencies and installed dependencies in various environments.

One nice thing about using pip-tools's pip-compile command is that you no longer have to ensure all dependencies of the top-level dependencies are installed and at the correct version. Instead, you only specify the top-level dependencies in requirements.in and then compile the more detailed requirements.txt.

While this is arguably superior to having a single, manually-maintained requirements.txt file, it still feels overly complicated.

I have read suggestions to use a metadata-driven approach via setup.cfg or pyproject.toml and maintain the top-level dependencies there. I think this would be a positive change, as it would eliminate the need to compile the second file. Dependabot should still be compatible with projects managing dependencies via setuptools.

Another thing to consider related to this: the use of a dev-requirements.in file to track development requirements.
