Nico Weber 6151a251f5 Tests: Add test for lossless webp file using a color indexing tranform ...

The image is https://quakewiki.org/wiki/File:Qpalette.png in lossless
webp format with a color indexing transform.

I've created Qpalette.webp by running

    examples/cwebp -z 0 ~/src/serenity/tmp.ppm -o Qpalette.webp

built at libwebp webmproject/libwebp@0825faa4c1 (without
png support, so I first ran

    Build/lagom/image ~/Downloads/Qpalette.png -o tmp.ppm

to convert it from png to a format my cwebp binary could read).

This file also happens to explicitly set max_symbol, so it serves
as a test for that code path as well.
