Bunch of refactorings / Added support for Arduino Nano RP2040 Connect (#20)
* Close flasher after completing operations * Refactored and simplified Programmer - removed DumpAndFlash (it doesn't work reliably) - simplified ctx message passing * Removed now unused DumpAndFlash methods * Added Arduino Nano RP2040 Connect support * Fix upload problems * Fixed bossac init... ooops * fix import removed by error * bump arduino-cli -> include the latest updates in serialutils.go Co-authored-by: Umberto Baldi <34278123+umbynos@users.noreply.github.com> Co-authored-by: Umberto Baldi <u.baldi@arduino.cc>
