Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed.

In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

Ideally I would be able to kill this multiplier, as it could easily be derived at runtime. But, for now, just turned it up so that the analysis-oriented parser is better at parsing different bit rates.

Improved logic for detecting when all sense has been derived from a track to spot any repeated track, not necessarily the first one. That avoids sectors that run over the index hold and obscure the first throwing things.

Switched to populating the sector cache with everything in a track the first time anything on that track is requested. That avoids the problem whereby each request of a non-existent sector costs two spins.

Expands the [M]FM encoder to respect some new Sector flags: it will now wilfully make CRC errors, omit data, include data that is different than the ID's declared length, write deleted data, and can be commanded as to header/data gaps and what should be within them. All based around expanding towards the needs for reproduction of the CPC's .DSK file format.

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.
