"fan_speed" is not supported

[vlad-lisnyi]

OWNHeatingEvent and OWNHeatingCommand are missing handling for fan speed. The change of the mode to cooling sends the command to set fan speed to auto, but no other interactions are implemented.

My setup (with MyHOME integration in HA):
3 x MH201 -> 3 x KM4691

Symptoms:
KM4691 successfully changes modes, but no results if the fan speed is changed (unless I switch mode to cooling -> turns fan speed to auto).
