Expose "lights" property to Group and Scene

[MizterB]

Can you please include the lights property in the group class? Understanding which lights are in a group will be required to correctly map groups to scenes. This would allow us to address the following issue in HomeAssistant, where the Hue component is not correctly handling duplicate scene names.

home-assistant/core#13685 (comment)

cant stress my support for this request enough.
This seems not only to be the cause for the hue.hue_activate_scene issue (which needs the groups), but might very well be the cause for other Hue issues started after the same update (now 0.68.1) from 0.65 which worked very fine indeed.

reference here: https://community.home-assistant.io/t/update-to-68-0-1-how-to-debug-config-error-hassio-hue-setup/52224

ever appearing error in the log:

snippet:

among the many timing issues and Hassio not being able to load, and the lights switching between being recognized and unavailable state in the Hassio setup.

maybe this is because of home-assistant/core#13109, and apparently a feature rather than a bug, but the thing is the Hub isn't unavailable at all.. My system sees it on several ways. The Hue app, the router, Home-assistant rest sensor, etc etc. All showing the Hub being online and available, even the lights and all sensors. Its just the new Ha implementation that says otherwise...

Hope this gets fixed soon, let me know where i could be of any help.

To resolve the HA issue, the light property also needs to be exposed in a Scene. Pull request addresses both Scene and Group needs.

Fixed in #8 and released as 1.5.0

[MizterB]

Thank you! Will update the HA functionality once 1.5.0 is on pypi.

Published. Didn't see PyPi blocked last release because README was inproper format.
