Make farts and oxygen agent b more accessible

[RubberRats]

Maybe certain foods should make you extra gassy and be more productive to reduce spamming? Get some beans from botany & have the chef whip you up some bean dip or something.

Funnily enough, there's already something like this in the game. Reagents like eggs, beans, and fartonium increase the quantity of gas released per fart. Back around 2021-ish part of the meta for doing pipeburns fast was having one of the engineers go get buttburgers to speed the process along. No clue why people stopped doing it for fart harvesting. Maybe if a few more reagents were added to the list?
