Being able to create an archive isn't necessarily a critical feature
of JGit. I would prefer if this was broken into its own library/plugin
so that consumers have a choice of whether or not they want to include
commons-compress in their product. If they do, they can include our
archive support JAR and have it work. If they don't, it doesn't.

The pgm package is already once such case, pgm isn't normally bundled
for a consumer and therefore its OK to depend on it here.
