Add additional features for withers/autonametag

[eepyfemboi]

First of all, with autonametag, a list of names which it would always ignore would be appreciated because if "ignore named" is turned off, it attempts to rename the same wither infinitely. Second of all, a baritone passthrough for following withers and renaming them, and a similar ignore list for this as well. Third of all, for autowither, there should be a few new modes, such as stack, which builds a stack of 4 (or any chosen number) withers by building them sideways, and suicide, which uses baritone to go to an echest, find 3 wither skulls, 4 soul sand and 1 nametag with a chosen name, then returns shulker boxes (if the items were inside of shulker boxes) to the echest, builds/names the wither, backs off to survive the initial explosion, then aggravates the wither to have a chat death message.
