[Imports] Import / update of France postal codes and population

[Sébastien Mariaux]

Hi everyone,

I would like to have your opinion and advice on an import I'm planning 
as part of a company project.

It concerns population and postal codes of French cities and departments.
The import aims at updating population of departments and cities, which 
is currently based on the 2013 INSEE data (French public statistics 
agency) while 2016 data are available.
It would also add missing postal codes, using data provided by the 
national postal service (La Poste).

All input data are based on governments entities and under ODbL 
compatible licenses. We already wrote some simple scripts to get the 
required data. These are available in our public repository: 
https://bitbucket.org/high-testing/osm-data-import/src/master/ .

This would be my first contribution to OSM, so any comment and advice 
are welcome. I am not too sure what is the preferable way for this kind 
of import: using the API seemed the easiest, but I understand from 
reading the wiki that this is not often recommended.

Thank you all and have a good day!
