title: Notepad++ Insert characters every 2 characters of a string
body: <p>I have a string representing hex numbers, like this:</p>
  
  <pre><code>778206213082061D06092A
  </code></pre>
  
  <p>I want to get a string like this:</p>
  
  <pre><code>0x77, 0x82, 0x06, 0x21, 0x30, 0x82, 0x06, 0x1D, 0x06, 0x09, 0x2A
  </code></pre>
  
  <p>So every 2 characters, I want to insert <code>, 0x</code>
  Is this doable with Notepad++? </p>
