added US/Pacific-New zone

since it's used by so many customers and moment-timezone can't convert it.

The data used by Moment Timezone comes from the IANA time zone database and is re-compiled for each database release. The US/Pacific-New identifier was a long-deprecated link that was removed from the tzdb in release 2018a:

The default installation procedure no longer creates the backward-compatibility link US/Pacific-New, which causes confusion during user setup (e.g., see Debian bug 815200). Use 'make BACKWARD="backward pacificnew"' to create the link anyway, for now. Eventually we plan to remove the link entirely.

If you have many customers using that identifier, they should be encouraged (or forced) to use something else. US/Pacific-New was intended to represent daylight saving rules that were never actually made into law (reference).

Additionally, this PR only updates data/packed/latest.json. This is a file that's auto-generated by the build process. So the next data release will completely erase this change.

Yep, no-go, thanks @gilmoreorless
