0.4.0

New Features
Developed the capability to compile to javascript/wasm. This required adding a new file object (mem_infile) that enables the library to read a compressed image data stored in memory (as opposed to being stored on external storage device), and C wrapper that interfaces between C++ and javascript. The provided wrapper currently support decoding only, but this should cover the majority of applications.

Bug Fixes
A bug in the quantizer was fixed for the lossy path. This bug can manifest itself at high bitdepths, or a large number of decompositions.
