Feature Request: Change Wallpaper

[MintMain21]

This would be a nice option, to change the wallpaper with the theme. The closest alternative besides creating a different script would be the native "change wallpaper after x amount of time" option which does not take into consideration time spent in sleep mode nor actual schedules based on the time of day.

I've added an option to execute a user script on mode change, you can find an example to changing the wallpaper on https://github.com/bimlas/xfce4-night-mode#settings -> UserScript
