Selector0<T> class

A base class for custom Selector.

It works with any InheritedComponent. Variants like Selector and Selector6 are just syntax sugar to use Selector0 with Provider.of.

But it will not work with values coming from anything but InheritedComponent.

As such, the following:

T value;

return Selector0(
  selector: (_) => value,
  builder: ...,
)

will still call builder again, even if value didn't change.
