Sought: (i) to instruct the CPC that it should be a 664, not a 464, if given a disk image (at least until I have RAM paging implemented for a 6128); (ii) to support ROM selection within the CPC and allow paging in of AMSDOS.

Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring.

Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required.

Fixes: individual static analysers reset tapes, for potential successors. The ZX81 file analyser no longer overruns its buffer upon receiving a file that is shorter than 11 bytes.

Ensured that there is a subclass of file that is entrusted to load .O/.80 files, and that the code routes such files to it, noting that it should consider whether a ZX80 is required.

Adjusted Super Chip test to look for two portions of 128 bytes. It now spots Dig Dug and doesn't acquire any further false positives amongst the tested set. So failure to spot the Activision stack-based paging mechanism is now the only remaining failure.
