Automated flagging of common spatial and temporal errors in biological and palaeontological collection data, for the use in conservation, ecology and palaeontology.
This is motivated by the fact that small countries or provinces might be completely covered by their centroid and users might want to remove very small provinces because the resolution of their analysis does not require small areas to be removed.
Updating countryref.rda with area_sqkm.

Used sf::st_area to get areas from the polygons.
For some iso3 and adm1_code codes a area_sqkm could not be calculated.
Countries without area_sqkm
Provinces without area_sqkm
