Also added ability to push 1bpp bitmaps to a Sprite to support rendering
images on an EPaper screen.

Floyd-Steinberg dithering and basic graphics example added as first
ePaper demo.

Also had to mirror the coordinate transform.

The ESP32 now works OK with the RPi display.

This is stage one of support for ePaper displays from Waveshare.
Examples for 1 bit per pixel Sprites and 2 or 3 colour ePaper displays
to follow soon.

Array name close[] clashes with a ESP32 function name.
Renamed array to closeX[]

Macro name (transfer16) conflict with SPI library fixed
Smooth font option added to User Setup files
Narrow font 8 option added to User Setup files

Thanks to Phaedra on the Arduino forum for pointing this out.

Add interface driver macro
Add 8 bit parallel support
Add 8 bit parallel read support
Add ILI9481, ILI9488 and HX8357D drivers
Update version and ReadMe
Update Create_Font processing sketch
Add slightly narrower alternative font 8

User setups are now all based on the same template.
