WayOut

This is a small update that fixes some issues that were found in the initial release :D

• Adjusted pathfinding logic to more consistently work deep underground
• Added fallback behavior of determining the most efficient vertical exit, in case an open route cannot be found
• Adjusted route scoring so that swimming up waterfalls is preferred over towering up with blocks, when possible
• Fixed bug causing the route search to restart on every position change of the player, causing pathfinding to repeat and never finish until the player stands still
• Significant performance improvements
