Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.

Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.

Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.

The 6560 is now a ClockReceiver. This reduces to zero the number of remaining instances of the text run_for_cycles in this codebase.

Switched to use of std::vector in those few remaining places where I was still using a unique_ptr to a native type and newing for myself. So, some of my earliest bits of code.

Gave the binary tape player a more logical assignment of wave level to output level. Which miraculously appears to have been the issue with the ZX80/81 tape loading — the inconsistency of silences seems to have been the issue.

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.

Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr.

Lengths I'd taken seem to have been for dipoles, not single poles. So I just doubled the clock rate. Also I was producing each dipole as high then low, when they should probably be low then high. The Vic now at least recognises that something is happening on the tape.

Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded?
