HyP3 autoRIFT v0.4.2

Fixed

• A partial fix was implemented to correct out of index errors when processing
  optical scenes (typically seen with Landsat-8 pairs) due to calculating different
  overlapping subset sizes when co-registering the images. Currently, only the
  smallest subset size is used, so the bounding box may be 1px too small in x
  and/or y, but there shouldn't be any pixel offsets. Full fix will need to be
  implemented upstream in autoRIFT.
