Add RP2040 binary that is automatically flashed during first boot #38
Description
During building, we create AR100, STM32F0-16 KB and STM32F0-32KB binaries. The STM32-binaries are automatically flashed during first boot. It would be good to also compile and save a Klipper binary for RP2040 which is the chip used in Remove and also Remote which is under development. The first boot script can get a list of connected devices and perform an automatic update of the software before starting Klipper.
