title: Readable file sizes with the Twig templating system
body: <p>I'm wondering if there's a built in way to output readable file sizes with the Twig templating system. Say I have something like this in my template:</p>
  
  <pre><code>&lt;p&gt;This limit is currently set to {{ maxBytes }}&lt;/p&gt;
  </code></pre>
  
  <p>How could I format <code>maxBytes</code> to display something like <code>30 GB</code>?</p>
