Add support Yeelight ESPHome

Thank you very much! I have some reading to do I see. And since the lamp isn’t where I’m at right now I will be itching to fiddle with it all :grin:
I know that there is quite a lot of irritated people with different kinds of lamps/bulb after this move by Yeelight and Xiaomi that broke their HA setup. I welcome you all to figure out ways to find good solutions with ESPHome and share your findings!
