Hex Casting Additions

This mod has some additions for hex casting to assist players in creating complex spells.Main additions are allowing spell circles to (almost[1]) infinitely repeat by using a delay, and adding new types of iotas for text (String Iota) and Items.

Most, if not all, of the information is documented in the hexcasting book, This is a preview

• Veil's Gambit: calls a list of iota s in the given delay, used for loops
• Item Swap: allows you to swap 2 items
• Author Purification: reads text from a book

[1] haven't changed native hexcasting code so if the delay isnt long enough it will still error
