Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator.

Sought to be more intelligent in handling cases where the two parts of a header or data field don't match — if either looks good then use it in isolation.

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.

Added reminder, ensured the couldn't-find-data case doesn't cause a crash. Though it should imply some manual investigation.

Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr.

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.

ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.

Turning this into a slog: gave UEF a more appropriate name, got as far as now having to decide what to do about ROMs as to structure. I guess they're machine specific, so specific classes?
