The "MFM...Byte"s aren't MFM-specific, they're relevant to both FM and MFM encoding. So renamed them. Also slimmed syntax within MFM.cpp mostly where emigration from the Acorn disk analyser had left a residue of lengthy namespace specification.

Decided that if this is an [M]FM parsing function then it should be something more intelligent than a mere PLL record. Which I guess conveniently implies Oric DSK-esque behaviour. But properly defined, rather than very vaguely.

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.

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.
