JPEGLS wip
Checkpoint of working JPEG-LS and JPEG-Lossless

JPEG-LS
=======

Port of David Clunie's C++ implementation
http://www.dclunie.com/jpegls.html

Limitations:
* Only supports gray scale
* Unknown support for signed vs unsigned
* Appears to have limited testing

JPEG-Lossless
=============

Port of the LOCI "BioFormats" toolkit.  Pure Java implementation, so port was straightforward.

Limitations:
* The "port" is more of a "wrapper", so it's slow
* Need to implement support for signed/unsigned and little/big endian
Removed dead code
Formatted source
Disabled logging
