Loading a profile & setting invidual backgrounds per monitor

In this example a profile is received via MQTT as string (e.g. Green.orp), set as active profile using the OpenRGB sink, and also used to derive different wallpapers for each of 2 connected screens.

Note the mapping transformation in the Transformations property of the Wallpaper sink. It has 2 mapping expressions. The first one maps the string Green.orp to the object {"0": "wayne-tower-green-led.jpg", "1": "batmobile-green.jpg"}. The wallpaper sink can consume these kind of objects, where each key is a valid screen index and each value a valid file path (which - given it is a relative path - is appended to the RelativeTo property on the sink). The second mapping returns a default wallpaper for all screens if no other mapping is matched. The mapping transformation always returns the to value from the first expression matching the input value.
