Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset.

Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more.
(obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).

Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that.

Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.

Confirmed: it is inaccurate for a 6502 to self reset at power up. So that responsibility now rests in the machines.

Corrections back towards composite output: fixed misnamed constant, ensured the CRT doesn't write nonsense to the output buffer, ensured it grows three vertices at a time rather than six when desired. Net effect should be that the output stage is working again, with the input processing remaining to fill in.
