Help adding E-Ink display support

i don't know if its best to put that into the library as code or ...

Interesting about the LUTs - yes, best keep them out of the library if we're targeting multiple devices. Maybe we could have separate library files with them in? For example:

var screen = require("SSD16xx").connect(
  {
    display: {
      bpp : 1,
      displaySizeX      : 200,
      displaySizeY      : 200,
      lutRegisterData   : require("SSD1681_lut")
      coloredDisplay    : 0,
    },
    ...
  }
);

One other thing to add - if you've got a big Uint8Array you can use E.toUint8Array(atob("....")) with a base64 encoded blob - it'll be quicker to decode than numbers and should take less space :)
