Attempted to implement Sleeper in Drive and therefore in DiskController. Also corrected a couple of nonconformant file names.

Sketched out a protocol designed to save processing time on anything that may sleep — probably just disk controllers for now but one can easily imagine it being applicable to printers, and possibly sound chips with suitable changes in guarantee for sound packet receivers.

Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'.

Introduced a test within the disk controller so as not to request illegal tracks from disks, instead automatically substituting an 'unformatted' track. Which is just empty.

Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14.

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.

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.

Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation.

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.

Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.

Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required.
