docs: Checks if json-stat version attribute exists and is equal or greater \
         than 2.0 for a given dataset.
  
         Args:
           dataset (OrderedDict): data in JSON-stat format, previously \
                                     deserialized to a python object by \
                                     json.load() or json.loads(),
  
         Returns:
           bool: True if version exists and is equal or greater than 2.0, \
                 False otherwise. For datasets without the version attribute, \
                 always return False.
