jpmapdata: Boundary Data for Japan Maps

Provides boundary 'GeoPackage' files used by the 'jpmap' package, including Japan prefecture example boundaries and official MLIT N03 administrative area data converted for 'jpmap'. Keeping these data in a separate package lets 'jpmap' update its functionality without repeatedly redistributing large boundary files on CRAN mirrors.
