Compress all output files for a rep.

An item rep may be written to multiple places, and currently only
one of them gets compressed by the gzip rule.

Unfortunately while nanoc maintains a complete output list internally,
it is not exposed in the documented API.  But it's not too hard to pull
out the guts and get the full list in order to compress everything.
