Packed data in 2019c.json is not the same as latest.json

[gilmoreorless]

While investigating #835 I found a separate problem with the packed data files. In version 0.5.28 the countries data was added, and the 2019c.json and latest.json files were updated to include the data.

However, the data is not consistent between the two files, despite latest.json claiming it's version 2019c.

$ git checkout 0.5.28
$ diff data/packed/2019c.json data/packed/latest.json

I believe I fixed that in 0.5.36, the data pipeline was messed up, esp around metadata, because the metadata was used but not yet generated, so whatever was latest.js that got picked up (pretty messed up).
