programs/games: Optimize GIFs (#235)

Browse Source

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`
QA with [GIF Inspector](https://movableink.github.io/gif-inspector/) and via code review.

📦 Program graphics (compiled or included with software):
- Slimmed `almaz/aniall.gif`, saving 380 bytes, ~9%.
- Slimmed `invaders/` 21 files, saving 1232 bytes, average ~3%.
- Slimmed `megamaze/orientg2.gif`, saving 986 bytes, ~31%.
- Slimmed `phenix/objects.gif`, saving 24 bytes, ~2%.

🥀 Old vestigial images, no longer used:
- Deleted `almaz/explode1.gif`, 4865 bytes.
