    Detail:
      Each Maestro file is held in memory as nine blocks of bytes: one for 'Gate' data,
      and eight for Note information for each audio channel. Maestro reserved a very big
      WimpSlot of 720K, and merely divided the space between the end of the program and
      the end of the Wimpslot by 9 to get equally spaced pointers for each byte block.
      This was very wasteful (Maestro files are typically only 1-2K in size), and there's
      no checking to prevent writes from running off the end of the Wimpslot.
      These changes
      - Add new memory management routines
      - Place all program data in resizable heap blocks
      - Remove EnsureRMA check
    Admin:
      Tested on a variety of Maestro files. There's still plenty of inefficiency in
      the way Maestro handles its data but typically, even with Sprites11 loaded, the
      Wimpslot goes down to 380K.
