Pruning some unused IDs

[Karol1223]

Summary

None

Purpose of change

Removing some unused IDs, or actually using them

Describe the solution

Affected IDs:

• mon_zandcralwer - removed from TropiCata on the notion of not fitting there, removed from DesertMod on the notion that the mod is obsoleted anyway
• mon_spinosaurus_bio_op - now replaces mon_spinosaurus in the DinoMod lab group, similar to how the tyrannosaurus is handled in that mongroup. @LyleSY please confirm that this is applicable, or tell me where else to put it
• feral_weapon_feral_m9 - removed, as it appears the monster that used it no longer wields that weapon. I believe Guardian changed the feral security guard in the past, and I think that's the monster that used it when I first added this attack

Describe alternatives you've considered

There's a bunch more unused content in DesertMod, but I feel bad removing more of it because a part of me still wants to revive that mod. Since it's obsoleted the tests don't run on it, so it can stay for now
