title: Simple-react-maps ignore invalid marker coordinates
body: <p>I have been playing around with react-simple-maps and was able to add markers using lats and longs.  about 80% of my markers are in the USA, so I am using this map here:

  <p>The problem I ran into is, when I pass it my data set, if it runs into a location outside of the US, it will fail but I can't seem to find anything that would let me ignore those markers.  I even tried to put the rendered inside the try catch block and it would still fail.  I would think that the code below inside me function component will just ignore bad/invalid coordinates but it does not.  Is there away to ignore bad or invalidate coordinates?</p>
  <pre><code> try {
          &lt;Marker coordinates={[-68.1193, -16.4897]}&gt;
            &lt;circle r={4} fill=&quot;#F53&quot; /&gt;
          &lt;/Marker&gt;   
        } catch (error) {
          
        }
  </code></pre>
