title: Select + hold and drag a shape should scroll horizontally or vertically
body: <p>I want a shape i.e. <code>Rect</code> select using the mouse (left hold and drag) should scroll it horizontally if goes to right side and if goes to bottom should scroll vertically in React Konva.</p>
  <p>If anyone has used trello, i'm trying to emulate the ability to drag horizontally using the mouse, instead of the scrollbar.</p>
  <p>This is my <a href="https://codesandbox.io/s/multiple-selection-react-hooks-and-konva-fq3fs?file=/src/index.js" rel="nofollow noreferrer">demo</a> where i have increased the width and height of <code>Stage</code>. While dragging it to right side. it should scroll and can be placed at last. If anyone knows how to implement it please answer.</p>
