The ZST archive is extracted into a temporary working directory and repacked as ZIP. Everything happens in a directory that is removed afterwards even if the job crashes, so nothing is left behind on the server.

What changes
- The ZST is decompressed to a temporary file and then packed as the single entry of a new ZIP archive.
