create, recall, and rename zigbee2mqtt scenes for a device or group over mqtt

Steps

1. Put the target device or group into the desired state (on/off, brightness, color, etc.).
2. Publish {"scene_store": SCENE_ID} (or {"scene_store": {"ID": SCENE_ID, "name": "..."}}) to zigbee2mqtt/[FRIENDLY_NAME]/set to save the current state as a scene.
3. Publish {"scene_recall": SCENE_ID} to the same set topic to apply a previously stored scene.
4. Use {"scene_rename": {"ID": SCENE_ID, "name": "..."}} to rename an existing scene, or {"scene_remove": SCENE_ID} to delete one.
5. Apply scenes to a Zigbee2MQTT group topic (not just an individual device) to control multiple devices with one recall.
