LimitedState class Null safety

Supertype for the three states that process pressed functions from LimitedOperations (which includes all NormalOperations). This is the contravariant typing relationship mentioned in our library overview. cf. the controller.operations library's class diagram, notably the dashed subtype line from LimitedOperation to NormalOperation.
