Walking towards improving opportunities for composition.

Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.

Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'.

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 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.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.

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.
