[Feature request] - more options for rotation direction
### Current Situation

I am new to homebridge, This program look amazing to me. I just tried a bit integrating my dyson fan into homebridge. 

I am trying to make an automation so that I can simple point the dyson cooler to me once I am siting in front of my computer. But I found that there is no interface for the plugin to accept rotation degree (360 degree )signal.

### Proposed Change

Can the service of `Air Purifier`, `Fan` and etc provide an extra optional characteristics for slider control to setup the rotation degree of the fan. So that plugins can help to pass this signal in the devices level
