Improvements to Oshan and Geothermal

[Scaltra]

some ideas, not mutually inclusive :
- hotspots under the station could be changed so mining does not boost them
- hotspots drifting naturally could “bounce off” station tiles and reverse direction unless intentionally pushed that direction by a stomper. (maybe still allow them to drift in a bit to do some damage on the sides sometimes)
- engineers could be given some sort of tool to un boost a hotspot. probably would have to be a slower over time style effect so you can’t mess up an engineer’s hard work too easily
- add the ability to deploy a vent capture unit on station tiles (i forget if this is already possible or not)

I love the idea of them bouncing off the station unless they were intentionally stompered toward it. This combined with the whole carousel system could make for a very fun and interesting new mechanic it could be renamed to "station system power booster" or something along those lines and it could boost that whole bounce off the station mechanic where at shift start with no boost it can only bounce off unpowered hotspots maybe? Then it could reflect increasingly higher intensity hotspots given more power. I both want people to use the current Carousel thing that exists and it to be better so my immediate thought is to combine the two anyway.
