[HEAVY WIP] Initial implementation of methane production

[Karol1223]

Summary

Content "Methane production chain"

Purpose of change

Methane production has been suggested a lot and @Drew4484 managed to fool me into doing this.

Describe the solution

For starters, adds a new furniture type - the biogas digester. It works kind of like a charcoal kiln except differently. The code, under the hood, is very similar. It takes in stuff made from specific materials (most common comestibles, dry plant, feces - the list currently is WIP and will likely be expanded) and processes them into methane. It also has a logic that, hopefully, excludes corpses from being put there because I don't want to deal with the process of having corpses leave behind bones or chitin.

In future commits I intend to add valves and inner tubes to make the construction recipe for the digester more inline with the real counterpart.

Describe alternatives you've considered

Testing

Okay now it should theoretically work but still don't get your hopes too high

Additional context

Huge thanks to @Drew4484 and @RenechCDDA for walking me through this because if I tried to do this all myself I'd probably cry

• This digester already finished producing methane.
• This digester contains %s %s of material, and the process is ready to be started.
• This digester contains %s, which can't be used to produce methane!
• This digester is empty. Fill it with organic matter and try again.
• biogas digester
• filled biogas digester

I am merely a humble contributor assisting others in copy pasting... I make no claims that I did anything good or useful here.

Closing for now so that when I have time to finish this I can reopen this myself. If stalebot does it I have to bully people with merge rights again...

Somehow, the biogas returned

Unless I'm missing something this isn't producing solid waste? Is that just not done yet or had you missed that facet of a bigoas digester?

Honestly both. The code for this right now is a mess (the C++ currently does not work, because I just copied over the gas pump code to have it at hand). I intend to come back to this and first and foremost make some way to get the methane out of the digester, and after that make sure it matches realism.
