Since this was the usecase, doing so simplifies the function significantly.

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

Check native object in case of early access 
If a native displayio object is accessed before it's super().__init__()
has been called, then a placeholder is given that will cause a crash if
accessed. This is tricky to get right so we detect this case and raise
a NotInplementedError instead of crashing.

Fixes #1881

Tweak pybadge and fix display bugs 
* Update pybadge pins and flash for rev D
* TileGrid now validates the type of the pixel_shader.
* Display actually handles incoming subclass objects.
* MicroPython will inspect native parents to see if special
  accessors are used.

4b3cb7b6db Expose displayio.Display.bus 
With the bus exposed, we can send custom commands to the display, to
leverage advanced features specific to the display, which are not
exposed by default.

A variety of displayio improvements 
This changes a number of things in displayio:
* Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with
  a font it is available as board.TERMINAL_FONT. Fixes #1172
* Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes #1191
* Add width and height properties to Bitmap.
* Add insert and [] access to Group. Fixes #1518
* Add index param to pop on Group.
* Terminal no longer takes unicode character info. It takes a BuiltinFont instead.
* Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history.
* Add x and y positions to Group plus scale as well.
* Add bitmap accessor for BuiltinFont

448ae64d8e
Add support for display rotation and raw commands 
Display rotation is relative to the scan order of the display.
The scan order can be found by scrolling the display with command
0x37 `display_bus.send(0x37, struct.pack(">H", i % 128))`
