Connor McLaughlin 1757932b3a GPU: Implement FIFO and timings 
This will cause a slight performance loss. I've left some knobs in which
can be tweaked to mitigate this, but the goal is to be compatible with
all games which require them.

Connor McLaughlin 05e4e7d262 CDROM: Add timing for speed changes/adjust seek timing 
This makes the BIOS take longer to load the executable off the disc,
giving the sound effects longer to fade out and reducing the overlap
with the game.

If nothing else, it'll avoid spamming the log.
 6 years ago
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 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.
