Radomir Dopieralski 102ee716a7 Add support for 9-bit mode to displayio.FourWire
If the ``command`` pin is None, that information will instead be
sent as a ninth bit in the SPI transactions.

Fix #6109

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.

Add polarity and phase to FourWire.
It was fixed as 0/0 even though it used to get it from the current
SPI state. This makes it more explicit with kwargs.

Thanks to magpie_lark and kmatocha on the Adafruit Support forum

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

Instead remember and use the frequency, polarity and phase that was
set when the bus was first created.
