opl: Handle negative time division values. A negative time division file indicates the MIDI file uses SMPTE time rather than the normal time system. This is not supported yet, but for the time being, return a sensible time division value that doesn't cause the sound to stutter and the game to become unplayable. This fixes #352, although the affected MIDIs do not yet play properly.
