My understanding is that there are four UPS zones, and you aren't indicating
which to use.  I would gather that the pj_init() is therefore failing because
it doesn't have all the required arguments.

I haven't dug into the PROJ docs to find what the correct formulation is for
UPS, but I presume that is the issue.
