docs: Facilitate annotating annotations received from the Client in the X-Tracy-Annotations HTTP header <br>
  Currently only supporting string annotations in CSV format. Example usage below:
  e.g.
  <code><pre>
  public void doGet(HttpServletRequest request, HttpServletResponse response)   {
  throws ServletException, IOException
  ...
  String httpRequestTracyAnnotations = request.getHeader(Tracy.HTTP_HEADER_X_TRACY_ANNOTATIONS);
  Tracy.annotateFromHttpRequestAnnotations(httpRequestTracyAnnotations)
  }
  </pre></code>
  @param csvAnnotations contains the annotations in CSV format e.g. key1,val1,key2,val2<br>
