  <p>Which is hexadecimal notation of bytes, hardcoded in as string format.
  I need this thing as a bytearray, importantly, not the ASCII representation of it, actually the hexadecimal values that is represents.</p>
  <p>All the kotlin methods I can find, such as:</p>
  <pre><code>val b = s.encodeToByteArray()
  </code></pre>
  <p>Seem to be taking the actual ASCII value of the string, and converting it to a bytearray.</p>
  <p>How do I create a bytearray directly from the values in this string?</p>
