Introduces ST730x series of display controllers.
These displays are epaper-like but with much higher refresh rate. They appear to have similar construction to epaper and lack a contrast control. Their readability is great until framerate is increased, then it drops massively at 51Hz, and looks fine up to 32Hz (the framerate is a specific setting).
(demonstrating loss of contrast at higher framerate)
Tested on shineworld/generic 4.2 inches st7306 and 2.9 inches st7305 B&W panels. This driver doesnt support color but it is a possible future addition as some models support many color and greyscale formats.
