Database: use official IGNF.xml registry to create content from the IGNF authority
Up to now, we re-processed the data/IGNF PROJ.4 definition to ingest it into proj.db,
but this file originally come from a processing of IGNF.xml
( http://librairies.ign.fr/geoportail/resources/IGNF.xml )
The end result is not strictly equivalent, as data/IGNF has some 'magic' to create
towgs84 / nadgrids, since IGNF.xml doesn't necessary contain all transformations
from its geodetic systems to WGS84. I've tried to re-add some of those missing transforms
(null Helmert transforms), so it can be used for pivoting, but that might be incomplete.
