[REQUEST] Energy detection scan with zigpy-zigate for ZiGate based adapters

[Hedda]

Requesting an "energy detection scan" feature in zigpy-zigate if possible matching what @puddly has recently added to zigpy-znp

Suggest implement similar channel energy scanning via some energy scanner tool but for ZiGate based firmware and hardware.

Energy scan

Perform an energy scan to find a quiet Zigbee channel:

$ python -m zigpy_znp.tools.energy_scan /dev/cu.usbmodem14101
Channel energy (mean of 1 / 5):
------------------------------------------------
 + Lower energy is better
 + Active Zigbee networks on a channel may still cause congestion
 + Using 26 in the USA may have lower TX power due to FCC regulations
 + Zigbee channels 15, 20, 25 fall between WiFi channels 1, 6, 11
 + Some Zigbee devices only join networks on channels 15, 20, and 25

@doudz by the way, I do not think this is related to https://github.com/zigpy/zigpy-zigate/issues/44

no it's a different thing

it's not currently doable with zigate because the Msg 0x804a doesn't provide energy information

it could be done but requires a firmware change https://github.com/fairecasoimeme/ZiGate/blob/master/Module%20Radio/Firmware/src/ZiGate/Source/ZigbeeNodeControlBridge/app_general_events_handler.c#L788
