Updates to Xcode11 recommended project settings.
...
The updated compiler also flagged a potential issue with CPU::Z80::Register not being a namespace re: 'Refresh' versus CPU::Z80::PartialMachineCycle. I don't entirely see it, but this fixes the problem.
I also finally figured out what the compiler was trying to tell me about ROMRequester.xib.

Differentiates reasons for a read to be four cycles.
...
Specifically, puts the enforced wait either before or after checking the wait line. More research may be required; it feels more likely to me that a forced post wait should complete the read then wait, but would that still count as a single machine cycle?

Expands documentation of NMI setting.
...
Given that it was previously incorrect, explains logic behind request_status_ and last_request_status_ setting. Also takes the opportunity to ensure that NMI is 'sampled' at the same time as IRQ; whether the next thing should be the NMI routine now occurs one cycle before the end of any instruction. That's an assumption for now. Testing to come.
