Expose modal position from useModalize hook.

[acalvino4]

Is your feature request related to a problem? Please describe.
Some of my Modalize children have display logic that depends on the modal's position. In typical react fashion, I manage the position state at the parent level - however, this leaves me imperatively updating it onPositionChange and onClosed. I image this is not a terribly uncommon desire, and some may even wish to access the position from outside the modal as well as in it's children.

const ModalWrapper = () => {
    const [position, setPosition] = useState<'initial' | 'top'>('initial');

    return (
      <Modalize
        onPositionChange={newPosition => setPosition(newPosition)}
        onClosed={() => setPosition('initial')}
        customRenderer={
          <Animated.View>
              <FlatList
                style={position === 'top' ? tw`hidden` : tw`w-screen`} // <-- logic depends on modal position
                renderItem={({item}) => (...)}
              />
              <FlatList
                style={position === 'initial' ? tw`hidden` : tw`w-[96vw] mx-auto`} // <-- logic depends on modal position
                renderItem={({item}) => (...)}
              />
          </Animated.View>
        }
      />
    );
  },
);

Describe the solution you'd like
The ideal solution would be, as the title suggests, to expose position from the useModalize hook, allowing me to drop my imperative state management:

    const {ref, position} = useModalize();
    // manual useState usage removed here

    return (
      <Modalize
        ref={ref}
        // manual state updating removed here
        customRenderer={
          <Animated.View>
              <FlatList
                style={position === 'top' ? tw`hidden` : tw`w-screen`}
                renderItem={({item}) => (...)}
              />
              <FlatList
                style={position === 'initial' ? tw`hidden` : tw`w-[96vw] mx-auto`}
                renderItem={({item}) => (...)}
              />
          </Animated.View>
        }
      />
    );

Describe alternatives you've considered
The alternative is to continue using my custom state management of the modal position
