as a complement to jpeg decoder, here is jpeg encoder from the
same author. surprisingly, it is more than two times smaller; i
took a look at it and decided: why, we should have both!
author claims that is supports baseline grayscale and RGB jpegs.
i tested it on some images i have, but no heavily testing was
done. it *should* work, though, as it is straightforward port.
it is completely independent of decoder, and self-contained.
unlicense, the same as encoder. yep, i know, i know, i'm very
sorry. fork it and relicense!
