[MERGED PR] Chemical production rework

[Asterion0]

After messing around with some of this, gotta say it's VERY fun. Genuinely love all the things so far, and absolutely adore the pustules (please let me put a hat on one). Styptic being changed means that if you put in some literal legwork, you can make a lot of styptic from very little, which is always cools. Oil being the way it is now perfectly fills the justification for condensers existing, as it makes it much simpler to do than it would be without it. The changes to some precursors are also very interesting for longer chem list productions, along with the way that the salbutamol and painkiller changes work. For anything to be expanded to, I'd like more things like the phenol+acetone reaction with some byproduct to deal with or use for chain reactions, along with said salbutamol+painkiller recipe, as it's a very cool concept.
