Connor McLaughlin 08ad5aad53 SPU: Run muted voices when IRQ is enabled 
Fixes SPU timeout in Casper. We can still optimize for most games where
interrupts are not used by completely ignoring muted voices in those.

Connor McLaughlin 18cc3d5932 SPU: Stub out external volume registers 
If nothing else, it'll avoid spamming the log.

Connor McLaughlin 4c2597acf3 SPU: Process key on/off at next 44100hz cycle 
Some games, particularly CART World Series and Monkey Hero, depend on
this behaviour.

Connor McLaughlin 7ac48cd8d6 SPU: Swap read/write ready bits 
Nocash might be incorrect here.

Connor McLaughlin 8e20d0d4ff SPU: Add audio dumping support 6 years ago
Connor McLaughlin 6a6aa72f3a SPU: Add a tick counter and delay between key on/off writes 
Not yet tested on hardware. We believe that writing to a specific
voice's key on/off register within 2 samples/ticks of the first
write will result in the second write being ignored. This still
needs to be tested on hardware for confirmation.

Thanks to @PSI-Rockin for the idea.

Fixes sound effects in Monkey Hero.
