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.

Fixed multiplier: the dot clock I've used to instantiate the CRT is the pixel clock, not the character clock.

Made basic attempt to get something on screen: white where the display is enabled, black for the border.

Transferred ownership of the CRT to the CRTC bus handler, to give it easy access.

Corrected CRTC timing, gave it someone to talk to and a means with which to talk.

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.

Made a first attempt at ROM paging, with pretty much the same scheme that'll be needed for 128kb support.

Added a first attempt at output port decoding. Just logging for now.

With a very basic stab at something a bit like the memory map (sans paging), execution begins.

Ensured that ROM images are loaded and passed to the Amstrad CPC.

Added the basics necessary to get the CPU ticking over, at a nominal 4Mhz but with the wait states that I currently believe to be accurate.

Added an instance of Outputs::CRT::CRT. So progress is now: select CDT, up comes a blank window.

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.
