v2.3.0 fixes doubling time bug

### Releases v2.3.0

1. Fix doubled time for ESP32_C3, ESP32_S2 and ESP32_S3. Check [Error in the value defined by TIMER0_INTERVAL_MS #28](#28)
2. Modify examples to avoid using `LED_BUILTIN` / `GPIO2` as it cam cause crash in some boards, such as `ESP32_C3`
3. Use `allman astyle` and add `utils`
