Description

Would love to see JBIG/JBG/JBIG2 implemented as supported files. They are relatively simple lossless raster formats (https://en.wikipedia.org/wiki/JBIG), seems like a fun challenge.

There is already an opensource C library, made by a Cambridge Prof, that supports this as well (https://www.cl.cam.ac.uk/~mgk25/jbigkit/).
Here is the patent information (http://www.iso.ch/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=19498&ICS1=35&ICS2=40&ICS3=).

Research direction

The issue names no Pillow files, tests, or entry points. Start by reviewing Pillow's existing supported raster formats and the referenced jbigkit library; done should mean JBIG, JBG, and JBIG2 files are supported.
