WiFiManager_NINA_Lite_SAMD.h
For SAMD boards using WiFiNINA modules/shields, using much less code to support boards with smaller memory
WiFiManager_NINA_WM_Lite is a library for the Mega, Teensy, SAM DUE, SAMD and STM32 boards
(https://github.com/khoih-prog/WiFiManager_NINA_Lite) to enable store Credentials in EEPROM/LittleFS for easy
configuration/reconfiguration and autoconnect/autoreconnect of WiFi and other services without Hardcoding.

------- ----------- ---------- -----------
1.0.0 K Hoang 26/03/2020 Initial coding
...
1.6.0 K Hoang 05/01/2022 Configurable WIFI_RECON_INTERVAL. Add support to RP2040 using arduino-pico core
1.6.1 K Hoang 26/01/2022 Update to be compatible with new FlashStorage libraries. Add support to more SAMD/STM32 boards
1.6.2 K Hoang 18/02/2022 Optional Board_Name in Menu. Optimize code by using passing by reference
1.6.3 K Hoang 20/02/2022 Add optional CONFIG_MODE_LED. Add function to signal system is in Config Portal mode.
1.7.0 K Hoang 27/04/2022 Use WiFiMulti_Generic library for auto-checking / auto-reconnecting MultiWiFi
1.7.1 K Hoang 27/04/2022 Fix bug for RP2040 using arduino-pico core
