Implemented EX HL, (SP) so as, allowing for indexed pages, to bring issues below the psychological 100 barrier. To 99.

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.

Timing fixes: the fetch-decode-execute pattern is now per-page, since that on [DD/FD]CB not only doesn't increment R but doesn't take four cycles, so is probably a normal read cycle. Adjusted timing all around.

Seeking proper [F/D]DCB emulation: the offset comes before the final byte of opcode, and adding seems to overlap with the opcode fetch, which does not increment R. Also needs to duplicate the result to visible registers.

Found a form I like for indexed addressing, applying it only where obvious for now. Which eliminates more than a couple of hundred of remaining failures.

After hitting my head against the wall of trying to use [NS]Scanner as a parser some more, have given up and transcoded the two tests files to JSON.

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.

Fixed Z80's ownership of its fetch-decode-execute program, its habit of scheduling invalidly when hitting an unrecognised operation and the test machine's habit of dereferencing invalidly.

Added a compact and copy stage for instruction pages, both [mostly] eliminating the mistake of letting static data structures contain pointers to instance storage and opening the door for addition of the DD and FD pages.
