The PixelFormat class has still an ugly byte array as the common part. This might need a bit of work. Also unit tests are missing.
This allows for another metadata class to be present: one for the IFD and one for the image header metadata.

This PR adds a Bio-Formats module named
ome-jxr. This module implements part of the ITU-T T.832 recommendation for "Still-image compression – JPEG XR". The main blocker encountered during work on the business logic was the lack of proper bit-level stream readers in Java (and Bio-Formats). The code implements the specification up to point 8.4.22.6. Comments have been left in places where the requirement of an enum or class was unknown before the decompression stage. Outstanding tasks can be seen in https://trac.openmicroscopy.org/ome/ticket/8493.For discussion during code review:
WARNING: This implementation is incomplete. Please see the comment below for the current status (March 2016)
