Enable Pure Converter

See non-working code in publications.md

## Publication List

<div id="publicationlist"></div>

<script language="javascript">

  var purexml_SERG = "https://purexml.ewi.tudelft.nl/convert/tu/research-id/ai4fintech";
  var page_nr = location.search;

  var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      document.getElementById("publicationlist").innerHTML = this.responseText;
    }
  };
  xhttp.open("GET", purexml_SERG + page_nr, true);
  xhttp.send();
</script>

Fails due to CORS issue:

publications.html:1 Access to XMLHttpRequest at 'https://purexml.ewi.tudelft.nl/convert/tu/research-id/ai4fintech' from origin 'https://se.ewi.tudelft.nl' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Same code works for publications in serg.delft and blockchain lab. Probably need to set some permission somewhere for the different URL.
