  <p>
  If possible, a matching, more specific, CRD subtype is returned. Note, that CRD for
  specific communication types might expect certain characteristics on
  <code>data</code> (regarding contained data).<br>
  
  @param data byte array containing the CRD structure
  @param offset start offset of CRD in <code>data</code>
  @return the new CRD object
