Create temporary redirects for serials to legacy GGP site

For now we'll use the redirect from /serial/<id> to search results on the legacy GGP site. We'll start out with 3200+ hardcoded redirects. You can see them in the following CSV: ggp_redirect_list.csv

These come from the latest (Aug 15) MARC XML exports we have from Simon. To get the redirect URLs, I just took the 856$u. I filtered down only to URLs that were at host dlg.galileo.usg.edu. If there are multiple for one bib record, I took the first.

The identifier is almost always the OCLC number, but technically it's whatever would be put in the slug field by our serial importer in DLG Admin. If that can't find the OCLC number, it uses the MMS ID, but that's a tiny edge case. Anyway, no harm in having a few extraneous entries that never get hit.
