JI's Stuff

This is a reworking of https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/adapter.

Both versions will work on both a zero and an ordinary RPi. - Some 64-row panels have a fifth address pin, labeled E, either at pin 4 or pin 8. Use the corresponding solder jumper to accommodate those panels. Obviously, you cannot mix 32- and 64-row panels on the same chain. The zero version is meant to be plugged into an RPi Zero/ZeroW and then the whole thing plugged directly into the HUB75 connector. Obviously only the middle 16 pins are used, but the 20-pin header makes it a lot easier to properly…
