countries: people with commit credit mentions, filter by more|less than or equal to X commit mentions

[YesCT]

might be interesting to see the countries data filtered by, for example,
countries with people with more than 10 commit mentions
countries with people with 2 or fewer commit mentions
maybe also, by the number of people with commit mentions total in that country

might show if there is a difference per country of % of people who contribute that have repeat (or continuous) commit mentions.
