J1772 Hydra boards

Well, I think the v2.2 design for the Hydra is going to be the stable design for a while. I'm not sure what to do next, though.

If I had some hope that people would actually want them, I'd place a medium run order for 20 boards. That would have a pretty substantial impact on my costs, but I have yet to sell even one Hydra to anyone.

Step right up, folks, don't be shy...
