title: How to add title to Polygon using react-native-maps
body: <p>I'm trying to draw specific polygons in MapView, but I'm not sure how to add title to Polygon.</p>
  
  <p>I tried to search official documentation, but only Marker has title property, so I'm not sure if it's supported.</p>
  
  <p>Marker can be used something like this</p>
  
  <pre><code>&lt;Marker
      coordinate={latittude: x, longitude: y}
      title="I am Marker"
  /&gt;
  </code></pre>
  
  <p>so is it possible to add title property to Polygon like this:</p>
  
  <pre><code>&lt;Polygon
      coordinates=[{latittude: x, longitude: y},...]
      title="I am Polygon"
  /&gt;
  </code></pre>
