Simplify the early game transition from Mineral water to Mineral sludge

[Grubsnik]

A common pitfall for people new to Seablock is that they end up postponing the transition from generating ores from mineral water to using mineral sludge. Instead expending their starting materials into scaling up mineral water generation and then having to afk for several hours while waiting for resources to regenerate.

The hypothesis is that the current switch is too hard unless you clearly know what you are doing. The transition introduces a lot of new game concepts all at once, while also being quite costly in raw materials and space. In total the concepts you need to master are:

1. Needing a supporting technology (when you unlock Slag processing, you are still missing the "Water treatment" tech)
2. Needing to use a some of a ‘waste product’, while still disposing of the rest (oxygen and hydrogen to make sulfuric acid) (need to use overflow valves, while not necessarily having the tech for that unlocked)
3. Having a closed loop with external inputs for filter frames.
4. Needing to bootstrap a process from a different process (using washing to get H2S, turning it until Sulfur, and then not needing it any longer)
5. Recognizing a net positive multistep loop and needing a strategy for dealing with it (adding buffering/overflows in the SWW recycle loop)
6. Needing to deal with prioritized producers (or voiding the purified water output from SWW treatment).
7. Being space constrained (this is around the time the player will run out of starting landfill, and this build takes up a lot of space unless you know what you are doing)
8. Being resource constrained (a hydro plant costs a lot compared to all the other buildings the player can build at this point)
