Static GIF to PNG-8 conversion

[Commenter25]

#38 was rejected because there's no lossless GIF compression. However, I have a different idea. I switched to Ubuntu recently, but before then I had used PNGGauntlet. When you drag a GIF in, it converts it to a PNG with indexed 256 colors, and compresses it. This was extremely convenient for my workflow, as I used it to quickly convert Garfield.com comic strips to PNG format instead of the GIF format they're stored in. The file size was always smaller, and having static images in GIF format confuses a lot of platforms nowadays that see it and go "oh, a animation!" anyway.

A problem with this suggestion is animated GIFs (aka the only gifs still used, except by paws inc apparently), but perhaps those could be converted to APNG, or simply rejected as they currently are.
