Eliminates diamond inheritance of KeyboardMachine::Machine by typers.
Specifically by pulling the key action stuff into a purely abstract class [/interface]. Takes the opportunity to unpublish a bunch of machine details.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.

Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.

Supposing the TIA were implemented, this is (more or less) what the Atari 2600 would now look like.

Added some wiring for PAL/NTSC mode switching on the Vic, making an attempt to simplify the whole loop of having different clock rates.

Made a first attempt to implement the full top-to-bottom change of clock rates, giving the Atari the ability to change rate when it switches to PAL mode, as it should always have been.

Made an attempt at a full and thorough 6532 implementation (and got a bit more explicit about flag size in the 6502).

Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated.

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.

With no regard to performance whatsoever, endeavoured to bring sound to the 2600. It's very scratchy, so something is wrong.

Made a very basic stab at a couple of the tone generators, added straight-through path for the speaker when input rate exactly equals output rate.

Got the basic sound pipeline pumping, just enough for static-level audio seemingly to work. Berzerk VE says "intruder alert, intruder alert", anyway.

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.

Sprites are still a pixel off but better; made some attempt to move things outside of the loop.
