Ensured lengthy constant sync can't appear to be two sync pulses, regardless of other interruption.

Made an attempt at triggering vertical sync the expected number of time after it begins, regardless of total length.

With an eye towards being more accurate as to vertical sync recognition: acknowledged that the detection period varies between PAL and NTSC.

Standardises on `const [Half]Cycles`

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.

Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.

Revoked the operator bool() on WrappedInt as providing an indirect means for implicit but incorrect assignment to unwrapped ints. Got explicit about run_for intention and simplified HalfClockReceiver slightly by building a lossy and a flushing conversion to Cycles into HalfCycles. Adapted the all-RAM Z80 properly to return HalfCycles.

Attempted to nudge wait timing onto half-cycle boundaries, which expands the number of partial machine cycles the Z80 can post but pleasingly also regularises them. Switched the AllRAMProcessor to reporting half cycles by default and corrected all Z80 tests.
