incrementBrightness on Groups gone now? This used to be a thing...

[peterbaker]

Describe the bug After upgrading Hue Magic to v4, none of my dimming switches work on groups anymore. incrementBrightness is no longer recognized, or mentioned in the README. There's no mention of it's removal, what gives? Are we really meant to brighten individual lights? That's a nightmare.

Expected behavior The same incrementBrightness and decrementBrightness options in Hue Lights used to be and should be available for Hue Groups.

Please complete the following information:

• Node-RED version: 12.0.2
• Hue Magic 4.0.2 (with the message.js fix from some other issue)
