Use uv for python project management

[vhdirk]

I just forked your repo with the goal of fixing some bugs I'm seeing. The first thing that struck me is that you're not using any project manager, like poetry, pdm or uv. I've been working with uv for a while now, and I absolutely love it. It's insanely fast!
Would you be open to a PR for this?

What does it add/improve? Install the modules in requirements-dev.txt and done.

What bugs have you noticed?

What I find a big improvement of uv over requirements[-dev].txt:

• It's significantly faster
• it encourages contributors to use virtualenvs. A simple uv sync sets up a virtualenv with all requirements immediately installed
• You can enforce a requirement on the python version used (min, exact, max, etc). If not detected on the system, uv can automatically download it and set it up
• When using uv add <new dependency> it automatically checks compatibility with other packages and the requested python version
• It makes publishing to pypi significantly easier: https://docs.astral.sh/uv/guides/publish/#publishing-your-package
• There's support for optional dependency groups (although at this point, that is not much added value for Kapowarr)

While none of these arguments on their own make a great case for adopting uv, I do think the usability and how integrated it is makes it a very useful tool to adopt.
I've been developing with python for at least 15 years, and for me, uv really is a breath of fresh air. Python dependency management has always been a bit of a pain, but after all these years, this thing has fixed that for me. ( oh yeah, I am not affiliated with uv/astral at all. I just like it :) )

For me personally (and >99% of development is done by me), there is no need for uv. However, that does not mean that it's not useful for contributors.

If you set up the (configuration) files uv needs to work properly and update the CONTRIBUTING.md file so that everyone can follow commands to develop using uv, then I'm fine with it. uv must not become neccesary in order to develop the project though.

Just add the configuration files that need to be present so that users can initialise uv and have it be ready for use. Seems like that means some additions to the pyproject.toml file, a .python-version file and uv.lock file?
