Impliment a linter

Some suggestion are 

- [prettier](https://github.com/jlongster/prettier) if you implement a Webserver
- [clang-format](https://clang.llvm.org/docs/ClangFormat.html) for C++ code (arduino)
- [ruff](https://github.com/astral-sh/ruff) or [black](https://github.com/psf/black) for Python

Also add check during PR to make sure the code passes
