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.

Eliminated the PLLParser class. I think the proper abstraction if and when another machine requires PLL-esque parsing is probably to template out the Acorn wiring of a PLL to a Parser, and/or generalise the Acorn shifter. It'll be easier to decide when the time comes.

Abstracted the concept of an Acorn shifter away from being a PLLParser. The Acorn tape parser now skips using that class and uses the shifter. The actual Electron also uses the shifter. So the two are completely aligned. Net result: the Electron should successfully load exactly when static analysis was successful.

Another fix to deal with real-time fighting: allow 8 and 18 pulses to be recognised as 1s and 0s. That's because the hand-off from ROM routines to parsing may occur very shortly before the first pulse of a valid sequence, making it look like there's a ghost. A cleaner solution needs to be found, probably revolving around allowing parsers to be attached to tapes and therefore to run constantly.
