v1.8.0 fixes doubling time bug

### Releases v1.8.0

1. Fix doubled time for `ESP32_S2`. Check [Error in the value defined by TIMER0_INTERVAL_MS #28](https://github.com/khoih-prog/ESP32_C3_TimerInterrupt/issues/28)
2. Modify examples to avoid using `LED_BUILTIN` / `GPIO2`, `GPIO1` as it can cause crash in some boards, such as `ESP32_C3`
3. Use `allman astyle` and add `utils`
