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.

Threw a sector cache into my MFM parser, in an attempt to cut down analysis costs. Also made it aware of multiple heads.

Ensured SSD and ADFs are grown if required.

Added writing for Acorn ADF disks, plus appropriate TODOs in both similar bits of boilerplate.

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

Added just enough for a complete manual test of writing to a .ADF with the 1770 then getting the correct result parsing it back on the host side in order potentially to update a file.
...
... which means that now it's time to worry about when and how mounted files should actually update themselves. Which will make for some fun with threading, I dare say.

Experimentally marked ADF as writable too, immediately discovering a mistake in the analysing MFM decoder.

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.

Created a base class for the boilerplate fopen stuff, switched as many classes as possible to its use, switched to postfix underscores and non-camelCase names.

Switched to assuming a single-sided disk, moved out magic constants.

This'll do for getting the ADF into the machine.

Made a first attempt at Acorn ADFS support plus the start of a suitable analyser.
