DisplayModeSelector<R, A> class Null safety

Helper to select something based on whether the calculator's display mode is one of the int modes, or float mode. We use a factory template to pull off dependency inversion between the model (us) and the controller, for the sake of OO purity.

NB: In Dart, this isn't as statically type-safe as one might imagine, because Dart allows unsound covariant assignment, viz https://github.com/dart-lang/sdk/issues/45731 That's mostly harmless here
