Adds first, incomplete attempts to talk to a ScanTarget from the CRT.

a8645f80bf
Introduces 'non-exclusive' emulator-space keyboards.
...

The converters from source data to output pixels do not modify the source data. It's a shame there's no `restrict` in C++.

About face! There should be no delay on serialisation, but a delay on interpretation-affecting soft switches.

Starts to expand the range of supported 6502s.
...
This fully implements the NES 6502 because, well, it's virtually no extra work, and ensures that RDY takes effect on write cycles on 65C02s.
