consider populating country/regional leaderboards with OONI News sites

[redshiftzero]

suggested by tor: while we have some suggestions for sites to add here in PRs/Issues, another source for the county/region leaderboards could be OONI's test lists. The county-specific test lists (see: https://github.com/citizenlab/test-lists/blob/master/lists) have sites categorized, and one category is "News Media".

@redshiftzero Looks like these CSVs are pretty sparse, e.g.:

https://github.com/citizenlab/test-lists/blob/master/lists/de.csv
https://github.com/citizenlab/test-lists/blob/master/lists/fr.csv
https://github.com/citizenlab/test-lists/blob/master/lists/pl.csv

Could be a useful starting point for anyone working on manually expanding the per-country lists. Leaving off the web backlog for now.
