Settled on assigning to nullptr as the appropriate style for emptying shared_ptrs; fixed the Vic properly to release its output resources.

Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that.

So it sounds like the user-port VIA might actually be connected to NMI?

|
Expanded typing to include phase for machines that need to go through multiple keypresses to reach a certain state, expanded Vic to be able to type most things (still bodged on lowercase though), and to schedule a 'run' if it's supposed to be loading into RAM, spotting that opportunity actually to do so.

Made the base 6522 class more abstract: you must now opt-in if you want the IRQ line to be sent to a delegate.

Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys.

Attempted switching back to a square wave for the composite video and otherwise implementing what's necessary to get to that flashing cursor — the 6560 returns its scan line and the timing bits of the 6522 are appearing.

Decided to turn the 6522 into a template, since it's a per-cycle thing with variable behaviour. Added appropriate memory map callouts to hit the two in the Vic. Though they don't yet do anything.
