Trinkets Updated

Few more fixes and new apis, most notably:

• TrinkersApi#getDropRule
• TrinketsAttachment#getInventory(slotId)
• Restored TrinketsInventory#getAttachment
• (Breaking, but not used) TrinketSlotReference no longer holds SlotType
• TrinketsAttachment#getSlotAccess and TrinketsInventory#getSlotAccess to get valid slot access (or null)
• Rename TrinketRenderer#extractStates to TrinketRenderer#submit (ABI compatible via mixin)
• CrustyFroge (CurseForge) release as soon as they approve
