Upgrade to PySide6

[bitcoinlizard]

Are there plans to upgrade to PySide6? PySide2 appears to be deprecated and at the very least will not work with more recent versions of Python. I maintain the Arch Linux AUR package for HWI. This package worked well in the past but the PySide2 dependency makes it impossible to maintain this package with Arch. If there are no plans to upgrade to PySide6 I can request that this package be removed from the AUR.

I see that there is an open pull request for this which wasn't showing up in my search on GitHub for some reason. I will close this issue.
