* updated arduinojson to version 7.3.0, enabled comments within json files
* update ESPAsyncWebServer/AsyncTCP to the ESP32Async fork
ESP32Async/ESPAsyncWebServer and ESP32Async/AsyncTCP are much better maintained and it looks like a lot of bugs are fixed compared to the ESPHome version we used before.
* Arduino 3.x compatibility (while maintaining 2.x compatibility)
