PySide2 Review Request needed

[Richard Shaw]

I think I have the package in pretty good shape but could use not only a
review, but also some advice on the sub-package breakdown. I've tried to
mimic the PySide1 packaging scheme but with PySide2 all 3 parts (shiboken2,
pyside2, pyside2-tools) are included in one big archive.

The history of this crazy package is here:

https://bugzilla.redhat.com/show_bug.cgi?id=1634658

And the review request here:

https://bugzilla.redhat.com/show_bug.cgi?id=1701013

I'm up for a review swap but I'm not a Python expert, I just need this for
FreeCAD and no one else has stepped up to package this monstrosity.

Thanks,
Richard
