Ensured flag setting is atomic, removed duplication of interrupt request versus busy, found better names for the personality testers, unified delegate protocol.

Now that it can be more explicit, this should admit that it's '93-based, not '73.

It would appear the 1770 and 1773 actually differ in relation to the (non-sensical) ability not to spin-up for a Type 2, and whether a side compare can occur. So the WD1770 class now requires a personality to be specified. Which it singly fails to honour.

Of course, changing the IRQ enable may immediately change the IRQ line. Signal if so.

Interrupt enabling works the other way around I think, and both registers with only one bit defined should probably return '1' in all other places?

Gave the Microdisc a clock signal, added just enough of force interrupt to avoid a spurious belief that a type 3 command has started.

Okay, so it looks like both ROM paging flags are the opposite of what I previously had.

Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now.

Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos.

The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation.

Moved audio work back into its own thread, but this time it queues up an all happens only upon a flush. Hopefully to resolve synchronisation cost concerns.
