Add Home Assistant Lights support

[satgit62]

Feature request

I think implementing a native Home Assistant API LED hardware would be a great addition for Home Assistant users. Especially for those that have registered RGB LED lamps, via ZigBee USB sticks, and don't have a Philips Hue Bridge. Yes, I know that you can address Hue lamps in HyperHDR as separate instances directly via the Hue Bridge, but not everyone uses the Hue, but ZigBee USB adapters.

What problem does this feature solve?

This would make it possible to use all ZigBee RGB LED lamps registered in Home Assistant in HyperHDR. This would also solve the problem of using workarounds such as emulating the Hue Bridge in Home Assistant.

What does the proposed API look like?

The REST API of Home Assistant is well described. It can be found at: https://developers.home-assistant.io/docs/api/rest/

How should this be implemented in your opinion?

For each instance, it should be possible to select an entity for a single lamp in the LED hardware setup, taking into account the IP address, port, and authorization token of the Home Assistant.

Are you willing to work on this yourself?

I could test everything and compile it for other platforms like webOS and post the results here.

I mention all this because a first Home Assistant implementation in Hyperion.NG I could successfully compile for LG webOS and the results are acceptable for first try. See: hyperion-project/hyperion.ng#1763

Since most of the users I know are HyperHDR users, I decided to ask them if they would also make it available for HyperHDR.

Thank you in advance.
