When there are a lot of masked tiles you can save a lot of computing time by making sure that s2p doesn't try to generate a DSM for fully masked tiles. So if all values in the mask are False, is_this_tile_useful should return False, None.
I also added two lines to masking.py to avoid computing the border mask if all values in the raster mask are False already.
