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.

Fix up end of file and trailing whitespace.

This can be enforced by pre-commit, but correct it separately to make it easier to review.

Add support for grayscale displays that are < 8 bit depth.
...
This also improves Palette so it stores the original RGB888 colors.
Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly
useful for the SSD1306.
Fixes #1828 . Fixes #1956

Add OnDiskBitmap which loads pixel data straight from disk.
...
Also, renamed Sprite's palette to pixel_shader so it can be
anything that produces colors based on values (including color values).
Added a ColorConverter that converts RGB888 (found in bitmaps) to
RGB565 for the display.
Fixes #1182
