Witchworks 2.0!

This update moves Witchworks up to Minecraft 1.21.  Here's what changes (it's a bunch):

These things were removed (because they never worked smooth):
- Displacement stones
- The summoned trader
- The HUD for the broom

Essence management blocks now often require or dispense empty bottles; infinite XP machines are still very possible, they're just more complex now.

Wand creation was significantly revamped (the brewing stand is involved now!  There are potions and throwable pearls in the process!) and a whole host of bugs with wands were fixed.

Kilnbroom is much easier to use now.

Added:
- "Harvesting planter" that auto-harvests
- Hoppers pointing into the side of an altar now feed into the empty bottle slot.
- Bottle-root plant (like potter's root, but smelt it into bottles).
- A novice trade is now present among villagers that's you forking over a LOT of bottled XP for one emerald - and then they level up.  Because, look, it's fun to ovomantically bag a villager and then de-egg them at a cartography table, level them up and get those maps, and other bits like that.

Recommended:

I would fully recommend combining this mod with the Waystones mod, Structure Maps or Ancient City Maps to add those in, and a mod with some added furniture to dress up your base.  This mod gives you a lot to build at home; may as well dress it up.  It also spurs you to go on outings; why not add a bit more adventure to them, and a growing teleport network to facilitate them?
