Attempted to use the new get_cycles_until_next_event method to take some repetition outside of the PLL and drive event loops.

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.

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.

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.

If loading automatically, assume that whatever was in the machine target set up the machine and don't override it. Too dodgy? More thought required.

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.
