Follow up #2131: GPX upload uses external scripts to decompress zip/bzip/gzip files. To be on the safe side, some more input sanitization is required here.

We also need to improve zip file handling in general here, so people can't kill the server by uploading  funny zip bombs. https://github.com/openstreetmap/openstreetmap-website/blob/268a8cb06e0a4734b9cb226ecebcc8445be4a9de/app/models/trace.rb#L256-L268
