Random event that spans SWORD in the asteroid belt or debris field

[Ikea]

For those who don't know, SWORD was a random event boss that was spawned on the station z level, and began attacking the station (pr here) https://github.com/goonstation/goonstation/pull/3666. This random event was disabled because it overshadowed the round and just got tiring after a while. It is in my opinion, an incredibly cool asset with a lot of work put onto it and it sucks it just sits in the code unused. So what if instead of spawning on the station z level, it spawned in the asteroid belt/debris belt instead?

This would reduce the obtrusiveness while still being a threat to any miners/debris field scrappers. Since it now no longer spans on the station z level, it can also spawn earlier in the round, giving time to play with the loot. For the changes besides the z level it spawns in, it also should probably be rarer then the initial implementation, and instead of the recipes being in hacked manufacturer's they're in a manudrive SWORD drops.
