ATEM Extreme crashes with ATEM HD Chroma commands

[randallpacker]

If you send the standard ATEM HD USK Chroma commands (Hue, Gain, Y Suppress, Lift) to an ATEM Mini Extreme it will crash, since the Extreme has differently defined parameters (foreground, background, key edge, etc.) Not that you would want to do this! However, I did it by accident before I realized how the Mini has restructured the Chroma key paramaters.
