Convert stupid GeoNames RDF dump format into Ntriples

convert2ntriples.py

# script from https://github.com/rhasan/sw/blob/master/genames/convert2ntriples.py
# with some hacks to make it work for Python 3

# This script will take genames rdf dump available here http://download.geonames.org/all-geonames-rdf.zip
# and convert each triples to N-Triple seralization.
# The dump has one rdf document per toponym on every line of the file.
# The produced N-Triples will be written in geonames.nt file. The final geonames.nt file is approximately 13.21GB
