Decrease default trigger_ms to 40

This makes triggering faster, and 60 ms is hopefully unnecessary with
deterministic triggering. You'll still need to increase trigger_ms or
the per-channel trigger width multiplier for low bass below 50 Hz.

 - Rewrite the trigger algorithm to enhance determinism (#403)
     - Triggering still makes mistakes, especially when DC offset varies within a frame (eg. NES 75% pulse changing volumes). This may be addressed in the future.
+    - Changed default triggering settings as well.
