kuva missions spawn places

[sulusdacor]

there are several spawn places that are quite bad to put it lightly. either the enemies sit in a choke point and it is a a cluster of doom, or you don't see the kuva cloud or the kuva siphon starts without you having any idea where it even is. this is mostly a problem on missions on the infested ship and corpus ice shipgraveyard tileset.

improvements to fix this could be:

- the kuva siphon gets marked by lotus as soon as the message comes

- limit spawn places to larger rooms and have dedicated spawn places for siphons (this would make them easier to find and fix the invisible kuva clouds)

as a reference to show what the problem is and a problem spot (look at the minimap):
