Added ruff formatter

[indykoning]

Summary

This PR adds the ruff formatter to format and lint the code, saving review time on formatting and linting.
This PR only introduces and runs the formatter, so no functional changes should have occurred.

Checklist

• I've made sure the PR does small incremental changes. (new code additions are dificult to review when e.g. the entire repository got improved codestyle in the same PR.)
• I've added/updated the relevant docs for code changes i've made.

Hey @GraemeDBlue & @johanzander,
I've added the Ruff formatter from the previous PR.
Could you give it a try as well, see if the code still runs and looks as expected? 😁

[GraemeDBlue]

@indykoning Have tested the SPH methods and they all seem to still work as expected

This change breaks the min_example:

(.venv) JZANDER@GC2F7TJ7VQ PyPi_GrowattServer % python3 -m examples.min_example
Plants: Found 1 plants
Processing inverter: RKM0D7N04X
Saving inverter data to inverter_data.json
Saving energy data to energy_data.json
Unexpected error: 'NoneType' object has no attribute 'utc'
(.venv) JZANDER@GC2F7TJ7VQ PyPi_GrowattServer %

min_energy_history() has timezone as optional, but fail if it is not passed as an argument.

Not critical from my side as the HA integration does not use this specific function and everything else seem to work from my side.

Tested:

1. min_example
2. min_example_dashboard
3. tlx_example
4. tax_example_dashboard
