Got a bit more explicit with range returned by get_cycles_until_horizontal_blank and hence attempted a more thorough (/correct) version of WSYNC.

Made an attempt to introduce an intermediate buffer that ends up with a bit mask of all graphical components present on it, and to use that to infer collision flags and colours, based on playfield priority and colour palette. Immediately yielding: a blank screen. Good work!

Created a placeholder class for a factored-out TIA. There's a bit more it'll need to do, like vending (or receiving) a CRT but this is the full hardware stuff, I think.
