This PR updates the EPD3in7 driver in the following ways:
Adds 1bpp byte packing
Implements a faster data sending method which sends 4k chunks instead of 1 byte at a time
Adds partial screen update support (but does not turn it on - see comment on the function)
I've been testing this panel with a rpi zero, and the above (particularly the second change) makes it much faster.
Partial refresh would make it a lot faster still, but I suspect the partial refresh of this panel doesn't actually work (more on that in the code comments).
