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.
