Add support for the Waveshare 3-color ePaper module. In scope is a method for determining the proper driver on initialization so that a single firmware image can be shared between the two FRST computer prototypes.

Also in scope is the rendering of Red pixels found in frame buffer. (byte value 0xE0? -- RRRGGGBB? 11100000 == 0xE0)
