title: Generating unique file name using UUID in golang
body: <p>I need to generate an unique file name with UUID1.</p>
  
  <p>My current python code is:</p>
  
  <pre><code>uuid.uuid1().hex[:16] // i need 16 chars file name
  </code></pre>
  
  <p>What could be the golang equivalent?</p>
  
  <p>Thanks!</p>
