Nico Weber e212c20228 LibGfx/WebPWriter: Implement pixel bundling for color indexing 
If an image has <= 16 colors, WebP lossless files pack multiple
color table indexes into a single pixel's green channel, further
reducing file size. This adds support for that.

My current test files all have more than 16 colors. For a 16x16
black-and-white bitmap that contains a little smiley face in the
middle, this reduces the output size from 128B to 54B.
