Lhasa 0.0.2

Second beta release.

 * This version adds support for level 2 and 3 file headers. Lhasa
   should now be capable of decompressing most, if not all archives
   found in the wild.
 * A fuzz testing framework has been added for testing the
   decompression code. A couple of bugs have been fixed as a result

Lhasa 0.0.1

Initial version. This should be considered beta code, although this
first version should already be capable of extracting the majority of
archive files found in the wild. The main missing features are:

 * Lack of support for level 2 and 3 file headers.
 * Inability to create archives (only extract them).

These are features that I aim to add in future releases. Other future
features can be found in the TODO file.
