jpmap: Japan Maps with Insets for Okinawa and Ogasawara

Provides tools for drawing maps of Japan with prefecture and municipal boundaries. The plotting workflow mirrors the 'usmap' package and includes a transform that moves Okinawa and Ogasawara into visible inset locations. Boundary helpers build local 'GeoPackage' files from Japan's official MLIT N03 administrative area data <https://nlftp.mlit.go.jp/ksj/gml/datalist/KsjTmplt-N03-2024.html>.
