docs: Creates a default Measurement Set subtable. Any Table Description
      elements in tabdesc will overwrite the corresponding element in a default
      Measurement Set Table Description (columns, hypercolumns and keywords).
  
      if name is given, it will be treated as a path that the table should
      be created in. Set to subtable if None
  
      if subtable is "" or "MAIN" a standard MeasurementSet with subtables will
      be created.
