Performed the basic metadata and routing for opening D64 files. Realised that I wasn't actually necessarily catching exceptions properly for all file opens, and fixed.

Slightly updated comments, switched to 1540 ROM so as very slightly to improve loading time.

Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.

Switched to a much-more straightforward PLL. I think I'm just fiddling now rather than moving forwards. Probably time to move on?

Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower.
Started sketching out a DiskDrive class.

With a history of three pulses, this can track up a 10% sine variation in a 1010101 stream. So I guess this'll do for now?

Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.

Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation.

This is probably a valid test. But I'm not completely sure. Time to figure out what's happening on the 1540 end.

Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus.

Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.

Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.
