Add "Test" visualization to more easily discern which fixture is connected to which pin

[CymaSpace]

Possible implementation would be to drive all available pins (6 possible pins in the case of Audiolux Touring Controller connected to x2 power & data distribution units).

Each pin out would illuminate each connected fixture a different color. Set to a (changeable) default of 400 pixels per output.

i.e. // Power Supply 1 2 - Red 14 - Orange 7 - Yellow // Power Supply 2 6 - Green 20 - Blue 21 - Violet

A color coded key could be included inside the lid of each power supply for reference.
