... and I guess an instant maximal simplification is also easy if length ends up being 0

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.

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.

Added ability to query how long since the new interval was set to the timed event loop. Discovered that LCM will returning the net effect of the common factors only. Otherwise continued iterating towards time preservation.

Okay, it's becoming more apparent where the (very mild) complexity will be here. But started moving towards retaining rotation between tracks.

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.

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).
