  Static libraries emitted by Psy-Q toolkit (presumably.) Basically a container
  for Psy-Q OBJs, basically a header for the file, and an extra header / symbol
  table for each module.

  There are 12 unknown bytes before the symbol table, which likely encodes build
  time, and perhaps other things not shown on PSYLINK.EXE's extraction output.
  The format is unknown.

        # being tripped up by leading zero in counted strings (wtf)
