This is a much better way of dealing with being partway into an incoming event. Subject to eliminating overruns, of course.

Still by manual inspection: the time for the next event should be provisional until proven acceptable, allowing a proper measurement of time until exiting the period to be taken; also fixed the accumulated period error when seeking back onto the underlying track.

Made an attempt to come up with a data structure that actually makes sense (though perhaps this is textbook list rather than vector stuff? I guess it depends on the frequency I expect inserts to occur versus reads) and to implement inserts. Though the Periods aren't yet honoured.

Implemented a very basic PCMTrack test, nevertheless revealing an oversight in PCMSegmentEventSource related to improperly counting to the index hole if the final bit is set. Took that as a message that I should comment and document the event source.

Maybe TDD is the way to get over my activity block on this thing? Fixed the existing ArrayBuilder tests so that the tests target builds again, added an extremely trivial PCMTrack test, heading towards PCMPatchedTrack tests.

Opted to pass times by reference and added enough to PCMPatchedTrack that it could start being used by the disk controller, albeit that it doesn't work.

This is going to be a slow walk, I think. This class attempts to be the scratchpad which will hold in-memory track modifications.
