Add support for ShenZen HOMA controllers

[stblassitude]

There are two models: one line voltage dimmer (brightness) and a
configurable 24V four-channel PWM controller. Depending on the DIP
switches on the RGBW controller, it appears as a single brightness,
color temperature, or extended color device; or as a combination color
and brightness device (RGBW).

They are sold in Germany through Amazon:

• https://www.amazon.de/gp/product/B076KPQWFW 230V
• https://www.amazon.de/gp/product/B076K6VJ8G 24V RGBW

Which model is which light? Does the model of the 24V change when you change the DIP switches?
Could you please post the unknown light warnings homebridge-hue issues for each setting? If you’re on deCONZ could you post some screenshots of the device in the deCONZ GUI, showing the clusters?

Looking at the description, I would expect the 24V to present itself, depending on the DIP switch setting, as either:

• A colour light and a dimmable light (RGBW); or
• A single colour light (RGB); or
• Two colour temperature lights; or
• Four dimmable lights.

Best set subtype anyway - I should have done so for all lights from the start (see https://github.com/ebaauw/homebridge-hue/blob/master/lib/HueLight.js#L318) but this would be a breaking change, so I’m waiting for the next major/minor release.

I'll try to work with the DIP switches tomorrow; here's the output as it is right now. I only have Hue bridges.

In order of appearance: the RGB part, then the W part of the 24V RGBW dimmer; then the 230V dimmer.
