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.

This is as simplified as things seem to be able to get without breaking at least Northern Star. Joe Blade et al remain stubbornly broken but I'm not immediately able to determine why.

Believing the previous implementation to be overly complicated through premature optimisation, simplified video. It's slightly slower now. Will need work. Immediately to do: figure out how to deal with blank scan lines.

Fixed synchronisation — my two fields weren't of equal length, I wasn't breaking calls to the CRT upon 40/80 transitions, I had the wrong maximum run length. Now I just need to put real pixels back in.

Commuted some camelCase variables into more standard C++ underscore names; decided the best fix for the graphics output is to break it down into much simpler chunks. output_pixels is currently a placeholder that simply outputs blank so the current effect is that all data is missing but it should be easy enough now to put pixels back in.
