Implements ROM::Request::validate.
It now also validates ROM sizes, so can no longer take a const Map.

Starts to introduce a new grammar for ROM requests.
They can be optional, and chained together in AND or OR combinations. A central catalogue knows the definitions of all ROMs.

Baby steps: apply Z80 state.
As far as it currently is. Since SNA is leaving the PC at the default of 0x0000, this currently has no visible effect.

Switches the Electron to JustInTimeActor video.
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.
