[PATCH v2] Add m1bpp (monochrome, 1 bit/pixel) pixel format

[Drew DeVault]

This is useful for Wayland compositors on low-end displays - in
my use case, this is the Heltec 1.3" SPI OLED display. It permits
compatible Wayland clients to utilize a more suitable pixel format for
writing to the display for greater fidelity and performance.
