ocenaudio not starting under budgie (with a potential fix)

Describe the bug

Under budgie ocenaudio does not start. There is

QT_QPA_PLATFORMTEHEME=gtk2
QT_STLYE_OVERRIDE=gtk2

set. If you unset these it will start.

unset QT_QPA_PLATFORMTEHEME
unset QT_STLYE_OVERRIDE

But then it looks out of place to the rest of the desktop. I was able to fix this using a qt6 build of ocenaudio. The fedora package is linked against qt6. I made a package.nix that creates a version of ocanaudio that looks fine and works (see at the end). I do not submit this an pull request because:

I installed nixos the first time today, I have no experience with it.
I do not know if my version would work for most people
I have no experience with the nix-language

I renamed my package to ocenaudio-qt6, in case it makes sense to provide it as an alternative. I added the package as an overlay to my system, so I am happy with that.

Steps To Reproduce

Steps to reproduce the behavior:

Run budgie (on 24.05)
Start oceanaudio
It does not start

Expected behavior

It should start
