title: LazyColumn items mutual exclusive
body: <p>Say I have a list of items in a <code>LazyColumn</code> and they can all be selected. How can I make sure when an item is selected, the others are deselected (so only 1 item can be selected at once)?</p>
  <p>I was thinking about <code>interactionSource</code> but I'm not really sure how use it.</p>
