maybe better huffman table compression. haven't actually looked though

The magic is use mozjpegtran <:kekw:808717074305122316>

The `FileOptimizer` runs these apps on jpeg files: `Guetzli`, `jpeg-recompress`, `jhead`, `Leanify`, `ect`, `pingo`, `jpegoptim`, `jpegtran`, `mozjpegtran`

2021-08-18 05:35:23	Progressive scan script and huffman tables are the main things you can tweak in jpeg to improve compression
2021-08-18 05:36:55	Removing things like restart markers and padding also helps of course.
2021-08-18 01:26:13	no, restart markers are used when you do parallel jpeg encoding and they might make files slightly more robust against corruption (maybe)
2021-08-18 01:26:20	they are not really useful in practice
