Add board.DISPLAY to MagTag. Fix luma computation 
* Initialize the EPaper display on the MagTag at start.
* Tweak the display send to take a const buffer.
* Correct Luma math
  * Multiply the blue component, not add.
  * Add all of the components together before dividing. This
    reduces the impact of truncated division.
