USB2 'webcam' using RP2040

[Shylie]

I recently acquired a pico-ice devboard and have been toying with it to get video output. The easiest solution has been to have it act as a UVC 1.5 webcam, thanks to the TinyUSB library. I've managed to get 320x180 video transferred at ~10 FPS or so.

The RP2040 handles the USB interactions, and uses PIO DMA to read data from the iCE40 FPGA on-board. Initial prototypes were based on the USB video-capture sample. I've attached several videos from my time working on this up until now.

Thanks again for this great library! It's made this project super fun so far.
