v1.1.0 to use FlashStorage_STM32, etc

### Major Release v1.1.0

1. Use new efficient [**FlashStorage_STM32** library](https://github.com/khoih-prog/FlashStorage_STM32). 
2. Add support to new **STM32 core v2.0.0** and STM32L5
3. Permit auto-connect without waiting for Config Portal if stored data is valid and WiFi test connection is OK.
4. Update examples with new features
