Maintenance update
Changes:
- Disable listening to EVENT_STATE_CHANGED even with manual YAML.
- Add version tag to hacs.json & manifest.json, and declare a zip release file.
- Share event listeners for multiple sensors, and dispatch all event filters for each sensor derived from a specific event.
- Parse boolean values in event data, so "true"/"false" are processed as expected.
- Add default mapping templates for Philips Hue Smart Button.
