Hextra Patterns

# Hextra Patterns ~~My humor is impeccable~~ A [Hex Casting](https://modrinth.com/mod/hex-casting) addon with some extra utility patterns that really just shorten hexes. The new patterns are properly categorized and split across multiple entries in the hex book. Many of these patterns can already be done in base Hex with just a 2-3 patterns, they're just nice as shorthands. Some of them are more complex functions that would take multiple patterns to replicate in Base Hex. Check out the book and see what there is!
