Import the dither library 2.2.0 as wip/go-dither

dither is a library for dithering images in Go. It has many dithering
algorithms built-in, and allows you to specify your own. Correctness is a
top priority, as well as performance.

+dither is a library for dithering images in Go. It has many dithering
+algorithms built-in, and allows you to specify your own. Correctness is a
+top priority, as well as performance. It is designed to work well on its
+own, but also implements interfaces from the standard library, so that it
+can be integrated easily in a wide variety of situtations. It supports
+images that make use of the alpha channel, AKA transparency.
