LitTabView class

A screen widget allowing to navigate the provided tab widgets inside an surrounding tab view.

It implements the LitBottomNavigation as a view layer and the required logic for tracking the state and the for navigating between the tabs. The tab wiew will ignore the any overlapping widgets when using a keyboard by disabling the Scaffold.resizeToAvoidBottomInset. To reenable the resize when using a keyboard, set the resizeToAvoidBottomInset to true.

Accoring to Material Design's guidelines (https://material.io/components/), bottom app bars should be able to overlap when using the keyboard.
