Add a new Saltpetre recipe because industrial amounts are unpleasant to make

[ohjoy]

Tray chemistry is too slow for what I'm doing, which is reaching plant stats in the high 100's to low 1,000's. Infusion is mandatory, which is why I need very large amounts of Saltpetre.

I'm gonna guess you are infusing potatoes, since you mentionned it in your first post. Potato cells have very low capacity with weak potency scaling. It seems to be by design. So if you are trying to get potato cells that come close or even outlcass standard cells capacity, that would indeed require an absurd amount of saltpetre, even beyond Omega weed. But this is a potato cell issue, not a saltpetre availability issue to me.

As stated in my original post, this was originally a potato cell issue, but I came to realize that this is a general Saltpetre production issue from my experiences of trying to make Saltpetre with a full crew.
