Have withdrawn attempt to be clever with client notification here, as it was having no effect in the current environment, making it hard to build up any confidence.

Switched to more straightforward version of two-step loop, dealing with my mistaken dealing of when _master_divider&15 == 0 upon entry without adding an extra sanity check. Am also temporarily on non-modulo logic for tone generation, for a profiling test.

Added a dispatch queue-powered Apple implementation of the async task queue, removed any mention of skip_samples in the AY since it isn't implemented.

Sought both to [start to] optimise the AY and correct divider reloads. It turns out that conditionals aren't that troubling. But I can probably eliminate the counters.
