Library to upload and optionally execute firmware to a flashless RP235x (RP2350/RP2350A/RP2350B) IC using UART boot.
The RP235x IC MUST be configured for UART boot - see section 5.8 of the datasheet https://datasheets.raspberrypi.com/rp2350/rp2350-datasheet.pdf
Example usage is at the end of the UARTboot.py file.
