Lightmaxx Vega Shiggy Beam Wash

This fixture is already in the library and works mostly nice. However, I realized that the software does not use the white LED but rather combines R, G, B, which generates some unwanted rainbow effects in beam mode. Please add support for the white LED when the color is set to white.

Here is again the link to the manual:
