If asynchronous background processing is to occur on tracks then, given that they inherently have state, they'll need to be copyable, and ideally 'cheaply' (though it's not too great a priority). So started implementing appropriate copy constructors. Also introduced an extra level of indirection to PCMSegmentEventSource so that it can copy itself without copying the underlying PCMSegment, which is 95% of the heft of a track in all currently-implemented cases.

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.

Reimplemented PCMTrack to use PCMSegmentEventSource, eliminating code duplication.

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.

Switched PCMSegments to std::vector; ensured generated [M]FM tracks are correctly sized, thereby making sure the individual flux windows will be correctly sized.

Made an attempt to insert proper conversions to/from rotational speed. The Time class is now really turning into a full-on quotient. Might need refactoring.

Made an attempt to add the necessary extension to Track, with a concrete implementation in PCMTrack, to support time-based seeking, the intended mechanism for not magically spinning the disk back to the index hole upon every head step.

Made a first attempt at D64 support. Made an error somewhere but this should be 90% of it.

Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more.
(obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).

Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.

Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower.
Started sketching out a DiskDrive class.

Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.
