Made an attempt to implement HALT as an operation that merely leaves the PC in place, adding the Z80's output line. Included that flag in FUSE tests. Discovered that it does not think that HALT acts that way. Which is probably correct.

[DD/FD]36 turns out to be a timing error: offset calculation overlaps with value fetch. So the FUSE test was cutting off my implementation early. Fixed.

One failure was just PUSH AF due to throwing away the 5 & 3 flags at the start. Switched to throwing them away at comparison.

FUSE seems to have inconsistent ideas about where b3 and b5 come from in more-complicated BIT instructions. So I'm not testing them for now. Within that reality, reduced to 102 failures.

Tidied up, creating a holder for RegisterState and giving it deserialisation logic. This makes sense because a register state will also need to be taken from the outputScanner, and from the machine.
