Lossless optimization of GIF image files.
Processed with `gifsicle -O3`(extreme) or `gifsicle --no-loopcount` (when only minimal adjustment is permitted).
LZW stream optimized with `flexigif -p -f -a=1`. Methods selected to ensure optimal compression with final KPACK step, since better LZW may reduce LZMA used in bundling programs, using: `xz --format=lzma --check=none --lzma1=mode=normal,dict=64KiB,nice=273,lc=3,lp=0,pb=2 -k -c in.gif > out.lzma`
