LibGfx: Add the start of a JBIG2 loader
JBIG2 is infamous for two things:
1. It's used in xerox scanners were it falsifies scanned numbers:

2. It was allegedly used in an iOS zero day, in a very cool way:

Needless to say, we need support for it in Serenity. (...because it's
used in PDF files.)
This adds all the scaffolding, but no actual implementation yet.
It's enough for `file` to print the mime type of .jb2 files, but `image`
can't do anything with the files yet.
