Update GUI to PyQt6 (Fix for M1 and M2 OS X)

[JoepdeJong]

I've updated the code to use PyQt6 instead of PyQt5. This resolves compatibility issues on M1 and M2 Macbooks. Tricks with Rosette are not needed anymore.

I can't seem to get pyqt6 to work on my machine. Thanks for the contribution.

I'll come back to you at a later time.

Do you have a Unix based system? If you want, I can send you some setup commands if you are running it in an virtual environment.

Currently working from a windows machine.
But sure, I'll give it a shot. Had some version conflicts as well, so could you please include the versions?
Thanks!

[JoepdeJong]

Will do. I'll send you an update today or tomorrow!

After modification, it works perfectly, great!

It works perfectly from here (M1 macOS), thx for the fix!
Btw, it looks like pyside6-essentials is not automatically installed with pip, so there maybe some missing entries in setup.py.
