Use pyproject.toml with hatch

[getzze]

Modernize the building and testing framework:

• use pyproject.toml
• use hatch environments
• add test_script to test plotting figures -> added in Compatibility with seaborn 0.13 #155

To build: hatch build or python -m build
To bump version: hatch version minor
To test: hatch run tests:run
To test with coverage: hatch run tests:run-cov && hatch run coverage:run
To build and test docs: hatch run docs:all
To run examples: hatch run examples:run -- --plot_type=boxplot --data_type=df_with_group_and_hue

To test #155 I had to write the test_script.py file and it was very convenient to use hatch environments for testing. So I thought I should actually make a PR about it :)

I modified a bit the Github action so instead of calling hatch once to run all the tests, the workflow creates a matrix of python and seaborn versions (we could also add an OS matrix if needed, see https://github.com/platformdirs/platformdirs/ for the modifications to do).

Github runs matrix jobs in parallel so the tests are substantially faster.

I forgot to mention that python 3.7 is not tested (hatch was not working for me with this python version). It would be better to drop it, as it is EOL anyway.

[getzze]

Thanks for merging #155, I rebased this PR, all tests are passing now. I will check the jupyter notebook.

Reminder: minimal python version is set to 3.8

[getzze]

The notebook runs correctly with python 3.12.

I added support for python 3.13 (only compatible with seaborn 0.13), the tests are passing.

[getzze]

Coverage is working now!

[getzze]

@trevismd it's ready for review

[trevismd]

Ah forgot about this one... Do you mind if I cherry-pick this one independently?

[getzze]

Yes, sure!
If you are planning a patch release, I realized the README also needs minor corrections: mention that the last version is 0.6, should be 0.7.

closes #150

I moved all the source files to a src folder, which avoids some errors when running tests and building docs.

Also I added some linting scripts: typos , end-of-file-fixer and trailing-whitespace
