docs: Add a location which is not a country or region. Value is parsed and compared to existing locations in
          HDX. If the location is already added, it is ignored.
  
          Args:
              location (str): Location to add
              exact (bool): True for exact matching or False to allow fuzzy matching. Defaults to True.
              alterror (Optional[str]): Alternative error message to builtin if location not found. Defaults to None.
              locations (Optional[List[str]]): Valid locations list. Defaults to list downloaded from HDX.
  
          Returns:
              bool: True if location added or False if location already present
