v1.3.0 to add support to RP2040-based boards

### Major Releases v1.3.0 1. Add support to RP2040-based boards, such as **RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040**, using [**Earle Philhower's arduino-pico core** v1.4.0+](https://github.com/earlephilhower/arduino-pico) to use with or without Blynk/WiFiManager features. 2. Add support to RP2040-based boards, such as **RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040**, using [**Arduino-mbed RP2040** core](https://github.com/arduino/ArduinoCore-mbed) to use without Blynk/WiFiManager features. 3. Fix bug 4. Optimize code 5. Update examples with new features

 The **RP2040-based boards, such as RASPBERRY_PI_PICO**, are currently supported using [**Earle Philhower's arduino-pico** core v1.4.0+](https://github.com/earlephilhower/arduino-pico) with Blynk/WiFiManager features thanks to LittleFS support. 
 
-The support to [**Arduino-mbed RP2040** core](https://github.com/arduino/ArduinoCore-mbed) with Blynk/WiFiManager features will be added in the future using **simulated-EEPROM or LittleFS** if ready then. NOw you can use this core without Blynk/WiFiManager features.
