Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Decided to follow through on Cycles and HalfCycles as complete integer-alikes. Which means giving them the interesting range of operators. Also killed the implicit conversion to int as likely to lead to type confusion.

Formalised the reasoning behind the colour phase fix-up and made it an opt-in per-caller value. Only the Oric currently needs to opt in.

Fixed Oric SCART mode by having it change what it's giving to the CRT based on which shader it knows will be active.

Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.

Altered phase so that it now merely accounts for accumulated error across a frame. Can probably do better.

Meaningful text! Albeit with the initial 'O' of 'Oric' missing. I guess control codes and NMIs next?

Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.
