hdfeos5: calc/write latitude/longitude if missing in geometry file

+ save_hdfeos5: always write latitude/longitude dataset, and calculate based on metadata if missing in the geometry file, such as ARIA and HyP3

+ cli/save_hdfeos5: check the coordinate of input file

+ improved UNIT and fig title handling for HDF-EOS5 product:
   - utils.readfile.read_attribute(): while grab the UNIT, use the last segment of dataset name if "/" is used
   - view.plot_subplot4figure(): use the last segment as the auto figure title, instead of the 2nd one, to be more generic

+ view: improved auto figsize for subplots when there is only one row of subplots
