Makes disk head position explicitly something with sub-integral precision.

Also as a drive-by fix, corrects accidental assumption of 10 sectors for all MFMSectorDump descendants.

Introduces a new class hierarchy for disk images.

Increasing independence of format-specific stuff and generic caching without mangling them into a common namespace, and allowing in some cases for a decrease in read/write blocking.

After a quick bit of reading, discovered the virtual copy constructor pattern really is only a convention in C++, and conformed to it. Which hopefully gives copyable tracks.

Attempted to switch to an asynchronous means for continuous file updates. Testing with SSD, as usual.

Worked on the all-around framework for decoding sectors back from tracks when closing down a file. Hit the wall that the parser is more observant of CRCs than the WD. No, really. So I guess I have to stop avoiding that whole issue.

Extended Storage::Disk::Disk to permit write-back of modified tracks, exposed some interface via Storage::Disk::Drive.

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.

Improved naming: this now explains what, not the mechanics of how.

It probably needs a better name, but hastily implemented track caching at the Disk level.

Started on the SSD/DSD support. Realised I had ommitted multiple head support from my disk class. Fixed that.

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.

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