2nd Hotfix/minor update

Added

1. trade with a wondering trade or a cleric (journeyman tier) with (wt=5,c=8) Apatites to get one emerald.
2. New advancement named: "✨ Calcite"

To get this advancement, you have to collect every type of calcites from the base game & the mod
(warn: calcites from other mods won't count!)

Changes

Tags:

1. Added Apatite to tag "c:gems".
2. Added Focial to tag "minecraft:coals"
3. Added Cobbled Alienstone to tag "minecraft:stone_tool_materials"

Features: Calcite Blobs

Reduce the `"ore feature with size" from 33 to 8.

The reason for this change was that calcite blobs
were way too common and you could have missed some ores along the way.

This is the last hotfix before the next major update!
