M3EExpandableList class

A spring-animated expandable card list.

Supports three layouts via named constructors:

• default / M3EExpandableList.builder: non-scrollable Column
• M3EExpandableList.scrollable / M3EExpandableList.scrollableBuilder: ListView.builder
• M3EExpandableList.sliver / M3EExpandableList.sliverBuilder: SliverList.builder for CustomScrollView
