      The dictionary of the JSON serialized objects consists of:
      {
          '__type__': 'PathSpec'
          'type_indicator': 'OS'
          'parent': { ... }
          ...
      }
  
      Here '__type__' indicates the object base type. In this case this should
      be 'PathSpec'. The rest of the elements of the dictionary make up the
      path specification object properties.
  
      Args:
        json_dict (dict[str, object]): JSON serialized objects.
  
      Returns:
        path.PathSpec: path specification.
