Feature request - Hide fan light icon
Hi,

I'm using a Sonoff iFan04 to connect my Fan to homekit via the homebridge-ewelink plugin
https://www.amazon.com/dp/B09C21LX9R

Would it be possible to have a boolean in the config.json that will enable/disable interaction with the fan light? I've got hue bulbs in my ceiling fan so the fan light has to be on at all times to transmit power to the hue bulbs. However, it's confusing/redundant to have two light icons in the Home app: one for the hue bulbs and one for the ceiling fan light. I think Apple should give us the ability to show/hide icons in the Home app, but they don't. So I think a fix within the plugin is the only solution. 

It also makes the Home app show "Bedroom light on." at all times even though the hue bulbs are off.

* **Please explain your feature request in a one or two sentences.**
Remove iFan's light icon from HomeKit. Light should always be set to ON so that the Hue bulbs always maintain power.
