 * MADSPACK 1.0 (used by early builds such as the Rex Nebular demo) used
 * this real PKWare algorithm; MADSPACK 2.0 replaced it with MicroProse's
 * own "pFAB" compressor (see pfab.cpp). The two formats are unrelated
 * despite the shared "MADSPACK" branding, and this decoder is deliberately
 * kept independent of the shared pack_data()/PackList machinery in
 * pack.cpp (which every other MADS game relies on), so that adding support
 * for this older format carries no risk of regressing anything else.
 *
 * Ported from the public-domain reference implementation "blast.c" by
 * Mark Adler (zlib contrib/blast), which documents the format originally
 * described by Ben Rudiak-Gould.
