add witches table

this block could remove selected enchantments and curses from an enchanted book(for a price). I personely feel like I need this(or something similer) since I often get books that have desirable enchantments but other stuff that is kind of useless like getting feather falling and sharpness on the same book and I know im not the only one. The witches table could be similer to the enchantment table, to use you must put an enchanted book and dark matter(could drop from warden?) into the table and select the enchantment, the more powerful the enchantment the more dark matter it will cost.
