Subject: [PATCH] Increase the batch size of the calcium carbide producing
 reaction (#76788)

* Increase the batch size of the calcium carbide producing reaction with the arc furnace

Also makes arc furnace into an appliance, which mitigates issues with attempting such a power-intensive recipe without a power grid

* Update data/json/items/appliances.json
