Controlling the Light State
**Is your feature request related to a problem? Please describe:**

> No it's not.

**Describe the solution you'd like:**

> I would like to be able to control the built-in LED light and I did not see anything in the docs regarding a light. It would be great to create an additional switch accessory for this.

**Describe alternatives you've considered:**

> I looked at the [myq-api](https://www.npmjs.com/package/myq-api#) library, [which appears to support setting the light's state](https://www.npmjs.com/package/myq-api#setlightstateserialnumber-action), but it seems to be outdated and no longer working with the newest version of the MyQ API.

**Additional context:**

> My garage door opener is a Chamberlain B1381, but since all MyQ openers have lights, I doubt that's super relevant.
