Subject: [PATCH] Bsdtar has no explicit flag for xz decompression
At least as of Mac OS 10.13.6 the included bsdtar has no flag for xz
decompression while `z` means gzip decompression which is obviously
problematic for xz compressed archives.
I believe that any tar version on Mac OS that can decompress xz archives
also automatically detects compression formats. So `tar xf` should be
fine.
Fixes #119
