Started on the SSD/DSD support. Realised I had ommitted multiple head support from my disk class. Fixed that.

Switched PCMSegments to std::vector; ensured generated [M]FM tracks are correctly sized, thereby making sure the individual flux windows will be correctly sized.

Calling it 'number theory' probably isn't accurate but extracted the CRC stuff and started using it for [M]FM encoding.

Started sketching out basic MFM track encoding. Which possibly even means that the shifters don't need to be public?

This possibly correctly encapsultes the lowest level of FM and MFM rules.

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.
