Bunch of refactorings / Added support for Arduino Nano RP2040 Connect (…
Browse files Browse the repository at this point in the history 
…#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
