Necrotic Wake 2nd/3rd floor coordinates + support rotation in floor bounds

[Wotuu]

Blizzard themselves can't handle this by the looks of it? Zolramus is rotated 65 degrees, the map has north = north of the flying thing, but this is rotated. As a result your player icon does not show up on the map.

This causes issues for ARC. For now it seems to work okay ish but it isn't what it's supposed to be. I think the rotation is throwing the conversion to lat/lng off.

ss from the route that's in the unit tests.
