Added CRC checking to DFS comprehension; fixed a bunch of places where I'd used Objective-C's #import rather than #include.

Introduced a full container for disk catalogues, so as also to capture non-file information, and 'completed' (i.e. albeit that CRC checking is still absent) DFS catalogue decoding.

This is exactly as far as I'm going to get with DFS parsing today, I think.

There's no cache and no CRC checking yet, but this is probably a rough outline of an FM parser.

The error flag is no longer directly exposed. I also tweaked the Commodore import numbers just a touch. But I think I need proper calibration.

Factored out the stuff I expect to be common to this tape nonsense, started looking at the one currently-failing tape. More on the latter to do.

I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron.

I think this should lead to a full representation of files on an Acorn tape, but subject to is_at_end working.

CRCs are just stored reversed. Of course. So this should be sufficient to load each chunk of an Acorn file.

Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area.
