Industry – Peat and Bog iron

This mod makes vanilla peat (+ 2 new types of peat) into a valid resource you can use for industry.
Three soils have this property:
– Peat
– Black peat
– Moss peat
They all are marked as "clay" on embark location, and are collected and processed in the same way:
1) Mark a "clay" zone on top of peat soil.
2) Order dwarves to "gather clay" in Kiln.
3) Use "process peat" reaction in Kiln or Smelter.
Each smelting reaction produces 1 coke and has a 10% chance to produce a bar of iron (bog iron inspired).
If you like the mod, you will make me happy if you rate it and share it with your friends. And remember, Losing is Fun!

This mod needs vanilla files to function.
It edits vanilla clays and kaolinite to have extra [REACTION_CLASS:CLAY] and changes all vanilla claymaking reactions to respect this, to avoid peat usage as normal clay.
To those who are confused what it means: if you do not use other mods that alter vanilla clay reactions, it is compatible.
