Uncompatible version of addok-csv 1.1.0 with current addok 1.1.1 and falcon 3.1.1

[frodrigo]

Using both last version of addok-csv 1.1.0 with addok 1.1.1 fails on CVS upload with {"title": "Malformed multipart/form-data request media", "description": "unexpected form structure"}.
Using the falcon version from requirements.txt (3.1.1).

After digging into the code is related on how addok-csv try to manually parse multi-part. The change comes from this commit addok/addok-csv@7957042

The new code try to parse before the stream was consumed. But it is already empty.

Fall back to addok-csv 1.0.1 works.

Hello,

I confirm addok-csv 1.1.0 is currently broken.
We also have #734.

In production for adresse.data.gouv.fr and the upcoming Geoplateforme geocoder we use https://github.com/livingdata-co/addok-server for CSV capabilities.

If you want to work on a bugfix, you're welcome.
