Regional granularity

Country level comparisons are quite limiting, it is difficult to draw meaning about the impact of measures. For instance, mortality and intensive care cases on country level are under/over estimated, in regards to whether co-morbidities are considered, or after health system collapse. The statistics are much more granular in the case of the United States already in the John Hopkins dataset, the Italian regions or Swiss cantons. It would be good to build on the work here to go beyond a country ranking.

@loleg great - i think we could add these in here (or have separate data packages). wdyt we should do?
