Xaero's World Map

* Compatible with Xaero's Minimap / Better PVP 20.23.0 or newer. Version 21.3.0.2 is recommended.
* Reworked how region versions are used. Changing resource packs and map settings should no longer update the global version, hash codes based on resource packs and settings are cached instead. As a result, changing your resource packs or settings will only update regions that were not generated in the same conditions. This means a lot less map region reloading that leads to better performance.
+ Added 3D slope shading, which now also takes horisontal slopes into account. The old 2D shading (vertical only) is available as an option in "Terrain Slopes".
* Replaced accurate slope shading on region edges with approximate, to significantly decrease the number of region reloads, to improve performance.
+ Added a new setting "Reload Regions" for forcing a reload to all regions that you view after turning the setting ON. Each region will only be force-reloaded once, until you toggle the setting off and on again. This works similarly to what changing a resource pack does.
* Some optimizations to map rendering.
* Fixed Manual/Single map selection mode sometimes breaking after going from a Server mode sub-world to a Manual/Single world and switching the dimension on the Manual/Single sub-world to a dimension you've already been to on the Server mode sub-world.
* Fixed infrequent null pointer crash when joining a server with the minimap installed.
* Fixed symlink support in a lot of places.
