Ability to change toothbrush led colors

[Lash-L]

Is your feature request related to a problem? Please describe.
I thought a cool use case for this integration could be the ability to control the toothbrush color. Could be used for fun, aka make a rainbow of colors once you finish brushing. Or it could be used for communication, aka when the light is red, I haven't taken the trash out yet. Not sure about those use cases, but still think it could be a fun integration

Describe the solution you'd like
Ability to set to one of the potential colors and to turn the light on and off.

Additional context

I have determine that a0f0ff2b-5047-4d53-8208-4f72616c2d42 is the char that contains the led color. it is writable, so theoretically it could be changed via a gatt write.

white = bytearray(b'D\xcfc\x00')
blue = bytearray(b'\x0f[\xcc\x00')
turquoise = bytearray(b'\x00\xff=\x00')
pink = bytearray(b'\xb2\t\x1a\x00')
yellow = bytearray(b'\x80\xff\x00\x00')
orange = bytearray(b'\xfcp\x00\x00')

This could potentially be something like a RGB schema and we could unlock additional colors.

I have not found if there is a way to turn the light on or off yet. as just being able to change the ring while I am brushing (and not using pressure) may not be very helpful.

If anyone is aware of any points your toothbrush turns the light ring on other than

1. when you are changing the light ring color
2. When you start brushing

That may help with the process.

I will continue to update my findings in here, and if I can find a full solution, I will implement
