Might as well be consistent with divider loads.

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.

Fixed premature wrapping of the envelope, played about with whether that should be subject to a predivision by 256. It feels unlikely?

Commented and fixed mistake that would equate any noise divider > 32768 with 0.

Made an attempt to implement noise and envelopes. Not quite right yet.

Made an attempt to eliminate conditionals (running before I can walk?) and started edging towards an envelope generator.

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

Made some AY advances; it's now being polled for samples and collecting more information on what it needs to output.
