title: React-Native: How do I find file info for a ph:// uri?
body: <p>I'm using the CameraRoll in React-Native 0.59.3 to fetch photos from the library.  I get back the following information:</p>
  
  <pre><code>height: 3024
  isStored: true
  playableDuration: 0
  uri: "ph://CC95F08C-88C3-4012-9D6D-64A413D254B3/L0/001"
  width: 4032
  </code></pre>
  
  <p>How do I get the filename, filesize, mimetype, and normal URI from this information? What is the purpose of this new <code>ph://</code> uri?</p>
