Add support for new Stelpro SORB fan heater.

[EtienneMD]

This heater comes with an integrated Stelpro Maestro thermostat (SMT402AD) but since it lacks a humidity sensor, it continuously reports 0% relative humidity in ZHA.

This quirk removes the RelativeHumidity cluster from ZHA.

do we know if this is reported in a non standard way instead of on the correct cluster? Have you checked z2m docs to see what they support? Just curious.

[EtienneMD]

I could not find anything on this particular fan in Z2M. Documentation for the device makes no mention of any humidity reading capability. All I found online was this Smarthings handler that disables the humidity reading from both the Sonoma and Orleans(SORB) fans. I have not looked at DECONZ support.

If you have any ideas as to what I should look for, I'd be happy to give it a shot.

As this is meant for bathrooms, humidity reading could be quite useful for automations. I will try scouring the Zigbee.db for something that could correlate to humidity.
