Lambda `call.set_hs`

**Describe the problem you have/What new integration you would like**

Would like to be able to call `call.set_hs(hue, 100);` where hue is 0-360 repeating.
*Side note: I'm not sure if a while loop will lock up the device so this may be a wild goose chase*

**Please describe your use case for this integration and alternatives you've tried:**

Working on a "non-addressable RGB" rainbow effect using lambda.
