Changelog

Dropped support for Minecraft 1.16.x
Minimum required Java version is now Java 16 (required by Minecraft 1.17 anyways, you should have this installed already)
Added integration with MMOItems
- Recipe types may now be mmoitems:mmoitem which requires an item_type, id, and an optional amount.
Added an optional -f argument to /saverecipe to forcibly save the recipe file. If set, it will overwrite a recipe file if one exists at the given path
Added a new configuration option, EnforcePlayerDroppedItems. When set to true, only items dropped by players are allowed
Added a new permission node, alchema.craft. Default to all players. When revoked, players cannot craft items in cauldrons.
Added 3 new recipes for Minecraft 1.17/1.18:
- entities/glow_ink_sac: 50 Glow Squid essence, 1 ink sac = 1 glow ink sac
- food/glow_berries: 4 sweet berries, 1 glowstone dust = 4 glow berries
- ores/copper_ore: 2 copper ingots, 1 stone = 1 copper ore
"name" and "description" are now supported fields in all recipe files, but remain unused currently
