Autoformat Python and C code

[Xeratec]

Summary

This PR adds support for automatically formatting C and Python code using standardized formatting tools. This helps ensure consistency and maintainability across the codebase.

Added

• Autoformatting support for:
  • C code (via clang-format)
  • Python code (via black)
• Configuration files for clang-format and black
• Enable formatting check in CI
• make format target in Makefile

Changed

• (If applicable) Adjusted existing code to conform with new formatting rules

Notes

• Make sure to run the formatter on your code before committing with make format

@phsauter In case you do not like formatting the C headers, we can wrap the defines in // clang-format off and // clang-format on comments.

It looks like black is not installed in the tools container by default but pycodestyle is.

How strong is your preference for black or does it have some needed feature pycodestyle doesn't have?

And as a nitpick, I would rather have:

AlignConsecutiveMacros: true

In .clang-format, I think it looks nicer.

Sure, I can add AlignConsecutiveMacros: true. I could also switch to pycodestyle however this does not support automatic formatting. I will thus switch to flake8 which is a wrapper around pycodestyle which also supports automatic fixing.

Actually, I just realized that flake8 does also not support autoformatting. How hard would it be to include black in the next version of the tool container?
