Draft: Implemented passing framerate limit to KPipeWire
The file size of recorded screen captures can be massively inflated, if the screen has a high refresh rate. Limiting the framerate should mitigate the issue.
I have not tested the changes yet, as spectacle does not work correctly on my dev VM. I will try running it on bare metal later.
The CLI was extended with the F option.
The GUI was extended with a spinbox.
