v0.1 - Initial release

This is the initial public release. It was written for ESPHome v1.13.x, and has also been tested on the freshly-released ESPHome v1.14.

This release uses binary sensors for the button presses, and toggles those sensors' states quite rapidly to on and then off again when a button is pressed. ESPHome v1.14 has included (and/or documented) the ability to generate Home Assistant events, so the binary sensors will be replaced with HA events for the next release of this project.
