Test on Windows

[emilianbold]

On macOS (and, I suspect Linux) we get by with the command line unzip / tar.

We should test the module on Windows too.

Pure Java unzip should work, but it was never tested on Windows

tar.gz won't be unarchived at all on Windows (though... seems a low priority).

Tested on a Windows 10 32-bit machine and it downloads the correct arch package. Unzip also works with the pure Java version and through Cygwin (via git shell).
