v1.2.0 to add support to RP2040-based boards

### Major Release v1.2.0

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](https://github.com/earlephilhower/arduino-pico)
2. Update examples with new features
