Remove_duplicates.py ported to Python3


#1

I was in need of running the old script for removing duplicates with a current version of Python. As Mapillary changed the uploading workflow now to a happy-nation-instant-all-inclusive-solution it was not possible to do this seperately before optimizing the pictures with ImageMagick in a batch.
