Defers starting the macOS audio queue, and attempts to restart it upon packet loss.
Hopefully forever to vanish permanent audio loss?

Have withdrawn attempt to be clever with client notification here, as it was having no effect in the current environment, making it hard to build up any confidence.

Pulled away my crazy rationalisation of an audio queue into a circular buffer and decided just to trust the OS. This should reduce latency.

Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz.
