Pyqt5 to pyqt6 migration

[RaghavaAlajangi]

Intro

This PR aims to migrate the codebase from pyqt5 to pyqt6
This is needed because QtCreator does not support PyQt5. It is explained in the issue #165.

To do:

• Refactor code to be adopted to pyqt6
• CI/CD pipeline passed
• Tests pass locally (run pytest tests on your computer)
• update CHANGELOG

Thanks for this effort!
It riddles me that CI fails. For the linux runners, apt install libgl1-mesa-glx in the workflow might help, but for Windows and macOS I am not sure what happens. Can you run python -m shapeout2 --version from the terminal on your Windows machine? Maybe the __main__ module needs refactoring.

I will be able to take a closer look in one or two weeks 👍

I get the below result when I run the command:

$ python -m shapeout2 --version
C:\Raghava_local\GITLAB\forks\ShapeOut2\shapeout2\__main__.py:3: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html

OK, then the culprit is somewhere inside the __main__ module. You could try commenting things out or adding print statements to see where things go wrong.

Hi Paul,
I ran the application without any arguments like:

changed the below line in __main__

# window = ShapeOut2(*app.arguments()[1:])

window = ShapeOut2()

In this case, it is working. I can open the files and sessions. But, when I run the tests, they still fail.

Hi @paulmueller ,
I ran tests today without making any changes. Surprisingly, they were all passed.

[paulmueller]

The tests still fail. I narrowed it down to the instantiation of the AnalysisView class, which probably should be implemented via promotion in QtDesigner. I will merge your changes into a separate branch and work on it from there.

Thanks!
