migrate to pyproject.toml with hatch backend

[svmhdvn]

As per https://packaging.python.org/en/latest/flow/, this PR migrates klongpy to a modern pyproject.toml with hatch backend. This is the recommended practice going forward.

New workflows:

hatch build generates a distribution
hatch fmt ... lints and formats the project
hatch test fully runs all tests (and also measures code coverage with the -c flag)

All tests are currently passing.

Coverage report with hatch test -c:

Hello, sorry for not noticing this before. I've not seen hatch and will take a look. Thanks! I'm in the process of refactoring some things and will consider this.

[svmhdvn]

Sounds good, I'd like to help push this forward. I do think hatch will definitely help you ease some of your development tasks and make managing dependencies easier. Let me first rebase and test again.

Here's the latest test run.

Any updates on reviewing this? I still think it would be good to merge this.
