code: public void addTransientRange(String id, RowRange range) {
      String start = DatatypeConverter.printHexBinary(range.getStart().toArray());
      String end = DatatypeConverter.printHexBinary(range.getEnd().toArray());
  
      appConfig.setProperty(PREFIX + id, start + ":" + end);
    }
docs: This method is expected to be called before Fluo is initialized to register transient ranges.
