Add yeelink.light.lamp4 support

[syssi]

If you are able to enable the 3rd party app api via the yeelight app you could use the yeelight integration.

@syssi Should we expect support for the miio protocol?

[syssi]

Yeelight devices can be controlled via miio. I don't know the exact details. I assume it's the same protocol but no token is required as soon the 3rd party app api is enabled.
