Vendor globe.gl and its Earth textures

globe.gl 2.46.2 (MIT, three.js r185 bundled) and the NASA Blue Marble
and Black Marble textures from three-globe 2.45.3, copied once from the
npm registry; SOURCES.md records versions, licences and sha256, and the
bundled libraries' notices are in LICENSES-bundled.txt. The service
worker leaves the folder out of the offline precache: the feed loads it
the first time it shows the globe.
