Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning.

Strung up an empty shell that eventually should contain the 8272, and added appropriate IO decoding to the Amstrad.

Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.

Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.

It's barely an implementation of the 8255, but ensured that data is bounced into the PortHandler, conveniently assuming the interaction mode used by the CPC.

Formally transferred ownership of PIO accesses to an incoming template, and decided to start being explicit about how to specify the interfaces and provide fallbacks for optional behaviour for the new, clean generation of interfaces. A full-project sweep will inevitably occur but I'll try to tie off this branch first.

As per my keenness for cleanliness improvements corresponding to my ever-increasing C++ ability: turned the Amstrad into something that a factory produces, allowing me completely to hide a bunch of implementation details.

Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr CRT.

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.

It turns out that quite a few tests still rely on CSTestMachine6502JamOpcode. Though since it no longer works, that'll need to be fixed. In the meantime, fixed the test build process at least, as it's not really what this branch is meant to be invested in.

Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring.
