title: 'const' enums are not supported in storybook when using my Typescript Components
body: <p>I have a typescript component with an enum :</p>
  <pre><code>  const enum blah {
      one = &quot;one&quot;,
      two = &quot;two&quot;
    }
  </code></pre>
  <p>Without the typescript enum, the typscript component will compile and display correctly, but with the enum in the code it will not.</p>
  <p>How do I make storybook understand enums in typescript?</p>
