Replace `saqc.core.modules` by a pyi-file

Removes saqc.core.modules in favor of an auto generated pyi-file. The generator is part of the repo now and I also added an CI-check if the signatures changed.

I Tested it to work on emacs with pyright and Visual Studio Code, would be nice if someone could make a quick check, if PyCharm also auto detects and uses the provided pyi-file.

Closes #180 (closed) and #241 (closed) .
