title: How do I merge an array of Uint8Arrays?
body: <p>I have an array of several Uint8Arrays.
  Something similar to this:</p>
  
  <p><code>[Uint8Array(16384), Uint8Array(16384), Uint8Array(16384), Uint8Array(16384), Uint8Array(16384), Uint8Array(8868)]</code></p>
  
  <p>How do I merge/concatenate/join (not sure what the right term is) them to a single ArrayBuffer?</p>
  
  <p>The key here is that the output I need must be an ArrayBuffer.</p>
