mixin.logic.fast_rotations breaks Nyf's spiders

[owosoup]

Nyf's spiders mod allows spiders to crawl on roofs, not just walls, and makes spiders look natural while doing it.
So, they can rotate horizontally, but also vertically.
mixin.logic.fast_rotations interferes with that, and makes the spider model lock into a single orientation when moving.

When you spawn a spider, it appears looking in a random direction. But as soon as it moves, the model will get locked towards a specific direction. All spiders become aligned, they crawl backwards, etc.
