fix: add constructor that takes IHasInputs<T>

In order to satisfy the requirements for the `MessengerBase` class, the
`ISelectableItemsMessenger` class needs to take an `IHasInputs<T>`, as that is
the device that implements `IKeyName`. We may want to consider adding a
`IHasInputsMessenger` specifically for those devices that implement that
interface vs the `ISelectableItemsMessenger`.
