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.

Updated the SSD file format container to specify sector sizes, now that it's no longer implicit.

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

Removed unnecessary header — it's implied by being a child of FileHolder.

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.

Ensured that FileHolder gets a writeable file reference if one is possible, and records whether the file in hand is read-only. So now the SSD class can answer honestly.

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.

Modified SSD to ensure a fully-formatted surface is represented even if no track data is in the source file. This corrects the controller's sense of write success.

Added enough stuff that SSDs attached to a 1770 will now reach the entry point for writing.

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.

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

Edging towards SSD/DSD support. Hold on!

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