More Mindustry Eriker Challenges

I think there should be more mindustry challenges for the Eriker planet. For example there are challenges for some of the sectors on surpelo (also please make more) so it could also work like that with Eriker sectors

Then for non-sector challenges, I know there tectically are some, but there are only two and those are both really hard (one much harder than the other) and for a hard planet to master. So there should be Eriker challenges for all ranges of difficalty. 

Please consider this because I think people would like this
