In terms of compressed file size, I'm not sure anything is going to
beat xz by much if at all.
If we are going to consider other compression algorithms, zstd would be
the main one to think about, and the main benefit would be much faster
decompression speed in exchange for slightly larger packages than xz.
Whether that's worth bunding a new utility, I'm not sure -- I don't
know what fraction of our package installation time is decompression
Also, bz2 is particularly slow at decompression, so even xz is likely
an improvement there.
