Use moxie-zip instead of node-archiver

After switching to node-archiver, I noticed some issues with
zip file creation, where the zip would occasionally be corrupt.
This seemed to be more of a problem with other projects, where
only a single zip file was being generated at a time (unlike
the test environment for this project, where multiple zip
files are created in series).

I tried zipstream, which also suffered the same issues.

However, moxie-zip, while quite a bit slower, does actually
consistently write working zip files. I switched the code over
to use it instead of node-archiver.
