[2.1] More controllable lava tiles on Vulcanus

[Erfar]

Right now you can generate lava tiles on vulcanus by blasting nukes/nuclear reactor. But that generatres holes that are both kinda small, "roundy" and require a lot of deliveries. Please add an late game tech to just blast like 3x3 holes for lava. Maybe some sort of "deep charge" or something that could be either localy produced or produced with small amount of key resource imports
