switch to using uv in rhesus

[K-Beicher]

Process:

Delete the pyproject.toml file.
In the terminal, type out uv init.
Look at the Git pane and take what was removed and move it over into the new pyproject.toml file. You can mimic what was done here.
In the terminal, run:
uv add polars pyjanitor
uv add "seedcase-sprout @ git+https://github.com/seedcase-project/seedcase-sprout"
uv add --dev ruff commitizen pre-commit
Which will create the uv.lock file and install everything
