feat(rust): eight more minor map labels start hidden (D213)

Read from the Carbon rig regenerated at world 6000, seed 981448696, whose map
carries every built-in label: the three that were unverified (Oxum's Gas
Station, Mining Outpost, Ranch) are spelled as written. Adds Canyon B/C,
Lake A, Oasis A/C, Mountain, Train Tunnel Link and Abandoned Cabins, and a
test over that map's 51 real labels.
