Factored out from the UEF implementation the concept of being a tape that has a queue of pending pulses and manages that queue.

Created a base class for the boilerplate fopen stuff, switched as many classes as possible to its use, switched to postfix underscores and non-camelCase names.

Workaround for a weird bug that suddenly appears to manifest: gzgetc is returning the file name, not bytes from the file. Seems to be related to improper initialisation of the next field within the gzFile header. I can't immediately see where ZLib intends to do that so it's a bit mysterious. But the larger-than-8 readers could probably save time by reading in blocks anyway.

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

More or less rewrote, to use a filled-per-chunk buffer of upcoming pulses rather than working them out as requests come. Which is more straightforward — all the code for a particular chunk goes in exactly one place — and much easier to extend. So threw in a provisional 0104 implementation.

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?
