High-res mode hdfeos5_2json_mbtiles.py error because of missing X_STEP

[falkamelung]

I get this error in high-res mode:

There is an easy fix by inserting

try:                                                                        
  high_res_mode = attributes["X_STEP"] is not None and attributes["Y_STEP"] is not None
except:                                                                     
     high_res_mode = None                                                                                                                                    

I could commit this but you might want to fix this in a different way.
