VID/PID for a new samd21 board

[sarfata]

We built a board roughly based on the trinket m0 with IR receive/transmit capabilities. It's a shitty addon for conference badges. Hardware and software are all opensource: https://github.com/sarfata/shirtty-addon.

I am working on a PR to get this merged into master (#2294 is the first PR against 4.x but I will open a new one against master). Would be great to have a custom PID for this board. Thanks!
