Ayke van Laethem 4a9667ffef st7735: make the display generic over RGB565 and RGB444

Using RGB444 instead of RGB565 can speed up graphics operations by up to
25%, especially on slow screens. But for full support, all parts of the
driver need to be aware of the color format.

It's possible to do this using a regular configuration variable, but
it's unlikely to be very efficient. Hence the usage of generics.

ST7735 driver

There are multiple devices using the ST7735 chip, and there are multiple versions ST7735B, ST7735R & ST7735S. Two apparently identical displays might have different configurations. The most common issues are:

Colors are inverted (black is white and viceversa), invert the colors with display.InvertColors(true)
Colors are not right (red is blue and viceversa, but green is ok), some displays uses BRG instead of RGB for defining colors, change the mode with display.IsBGR(true)
There is noise/snow/confetti in the screen, probably rows and columns offsets are wrong, configure them with st7735.Config{RowOffset:XX, ColumnOffset:YY}

If nothing of the above works, your device may need a different boot-up process.
