Pulled the strands together provisionally to complete Commodore ROM-format tape parsing. Things are going to get complicated if or when I need to tackle turbo loaders.

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.

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?
