[Added] [Map] Castle Vacrul: Thirst for Power

[benjcallaghan]

This raid zone uses the same maps as Rosy Reverie and Caverns of the Forsaken. It starts where Rosy starts and ends where Caverns ends. These two other zones already have maps, and I would like to reuse them. However, the two ZoneRects overlap.

The attached mockup shows the combined maps as one large image. The part in blue belongs to Rosy Reverie while the part in red belongs to Caverns of the Forsaken. The overlapped region (roughly shown in purple) covers reachable areas of both maps, so priority alone won't help. heightmin and heightmax also won't work as the red region has both the lowest and highest reachable areas.

Does anyone have any suggestions how I can solve this issue?
