Optimizes Spell Circles

[Stick404]

In 1.20 Spell Circles can loop on their own slate, however this can cause massive NBT-Leaks due to the same positions stacking on the same positions. This PR just makes reachedPositions a HashSet/Set, and adds an extra Int Var of "reachedNumber", or how many slates it has come across (this is for the speed up of Spell Circles).

A total list of things changed:

• Removes the memory/NBT leak of Spell Circles
• Stores only the highest and lowest vectors of the Spell Circle bounds, rather than all found possible slate
• Removes an old Null Logger in Cleric Impetus
• Optimized Spell Circle scanning, instead of calling the normal getBlockState, which loads many more chunks, it now calls getChunkFuture. In case the future fails/does not work, it still calls getBlockState as a fallback
• Now respects the Slate Limit in the config

Went through these and fixed the local version. I'll make a push once there are no more random problems with the code
