Update DUMB to revision 7def196332594817f94138dce2942007d232d407

Browse source 
- Corrected volume slide behavior for S3M playback, and also adjusted the slide volume level clipping range for S3M to 0-63
    - Updated S3M playback to share memory between DEFIJQRS effects
    - Adjusted S3M reader to a lower master volume level scale
