Following issue #151, the French airspace file was updated on the http://soaring.gahsys.com website.
This PR updates the information about the French airspace.
Note sure about the update date: I set it to 2020-04-23 because the header of the file states the information source is "AIP FRANCE 2020/04/23". However, the file was uploaded on the French Gliding Federation on 2020-05-05.
