Fixed: individual audio generators now either are or are not stereo. The speaker acts accordingly.

Adds optional stereo output for the AY.
The real chip provides the three tone channels as separate outputs, so a variety of different mixings can exist.

Introduces active input handling for the AY and uses it in the CPC to give proper, active keyboard input, rather than push-on-select, which was only ever a temporary hack. Also maps a few more keys for the Amstrad.

Attempted to move to more accurate bus reading — if control lines are set then all subsequent data inputs should act according to the current control lines; changes to port input should be reflected live upon readings, etc.

Added the ability to set a port input, and relaxed bus state testing. I think my on-demand bus reactions here are inappropriate, so more work to do here probably.

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.

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.

Ensured propagation of synchronise messages, added enough to do plain tone. Probably. So: noise and envelopes missing. And it's all far too quiet.
