How to parse a json list of multiple type in Moshi
<p>Got a json list mixed with plain String and Image object like this:</p>

<pre><code> {
  "mixList": [
    "string",
    {
      "imageUrl": "http://...",
      "height": 320,
      "width": 480
    }
  ]
}
</code></pre>

<p>How to parse with Moshi?</p>

<p>I would expect to have a <code>List&lt;Data&gt;</code>,
where <code>StringData extends Data</code>
and <code>ImageData extends Data</code></p>
