Upgrade from PyQt4 to PyQt6 in Qskope

Overview

I wanted to use Qskope to see a KF file which doesn't get imported in NifSkope (This is not a normal .kf file; there should be only NiControllerSequences as root blocks). So I decided to use this Qskope app to try to edit my file. But this used PyQt4 which is a bit cumbersome to install. So I decided to upgrade it to latest, which is easier to install (pip3 install PyQt6)
