There's no cache and no CRC checking yet, but this is probably a rough outline of an FM parser.

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.

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.
