Ticket #144 (closed defect: fixed)

Right now, ND2 files larger than 2GB can't be opened. Although loci.formats.RandomAccessStream supports >2GB files, JAI's I/O classes do not. Possible solutions to this problem include:

1. Patching JAI to support >2GB files.
2. Native JPEG 2000 support, which allows us to use the existing I/O framework.
3. Find a different JPEG 2000 library that can support large files.

The advantage to (1) is that I don't have to write a JPEG reader. However, reading ND2 using JAI is *very* slow, so (2) would allow us to (hopefully) speed up access times.

(3) is pretty much out of the question. Every other implementation of JPEG 2000 is either based on JAI/JJ2000, or is not free (in either sense of the word).
