SDMX is a common format used to statistical data and can be used to describe codelist. eg https://ec.europa.eu/eurostat/databrowser/bulk?lang=en&selectedTab=codeList

Add possibility to import those codelist as SKOS format.

Filename must use extension .sdmx.

Tested and works fine.

For a future work, maybe to identify the file format we can do some checks on namespaces instead of relying on the file extension.

Yes, I was thinking of this in case loading thesaurus from URL directly. I'll check in another PR.
