This PR modifies
water_mask.py
such thatcreate_water_mask
is able to utilize the COG features of the water mask files in AWS. The improvement comes from subsetting the water mask tiles to the projection window of the input image. This means that GDAL only has to work with a small portion of the data, rather than the multiple GBs that the full water masks may take when uncompressed.This should address ASFHyP3/hyp3#2640
