v1.8.2 to optimize code, etc.

### Release v1.8.2

1. Optimize code by using passing by `reference` instead of by `value`
2. Optional `Board_Name` in Menu. Check [option to remove board name from web page #25](khoih-prog/WiFiManager_NINA_Lite#25)
3. Add function `isConfigMode()` to signal system is in Config Portal mode.
