Would it be possible to add (as Option in the Settings maybe or as addon mod) to add the additions from this old mod?

Its adding a research for Synthetic Pollution Collectors and some other things.
I know this would change the Mod for how its used, so it is prob. the best to give settings to enable/disable this based on play style.
It would also allow solutions for Fulgora with as example the Fulgora Enemies mod (electical based enemies) which would be weird to drop Xenomass.

As additional Idea but lower than my request above, a way to collect spores and maybe even have very different usage from this, fully up to ur ideas. Right now i use 2 Air scrubber mods (early game + Endgame) but would be nice to have an all in one mod for this.
