Detailed Description
Town with INSEE code 14697 seams to have disappear since 2003 but in fact it's a very special case were INSEE code has been reused and inverted with the "chef-lieu".
See #53 (comment) to have context where it has been detected
It seams to have something to do with https://github.com/etalab/geohisto/blob/master/geohisto/specials.py#L432-L459 which doesn't handle the 14697 INSEE code
