Title: Remove PackedNode/PackedElem classes

These have been obsoleted by the parallel.h packed data API for a while.

I was originally leaning towards just marking these as deprecated for the next release, but I don't think we've got any outside users of the class, we haven't used it internally for years, and it's been out of date at least since the unique id feature was added.
