docs: Set the dataset standard string type attributes.
  
          Args::
  
            label         dataset label (attribute 'long_name')
            unit          dataset unit (attribute 'units')
            format        dataset format (attribute 'format')
            coord_sys     dataset coordinate system (attribute 'coordsys')
  
          Returns::
  
            None
  
          Those strings are part of the so-called standard
          SDS attributes. Calling 'setdatastrs' is equivalent to setting
          the following attributes, which correspond to the method
          parameters, in order::
  
            long_name, units, format, coordsys
