fix: Cleans up LINQ calls. (#965)

- [X] Removes several `ToList()` uses with `PooledRefQueue`
- [X] Adds a `PeekRandom` to PooledRefQueue
- [X] Updates EV/BS so they dispel each other in a more efficient manner.
- [X] Fixes Firebomb so it works like a normal firefield.
- [X] Fixes field spells so they aren't unnecessarily using a Point3D ref more than necessary.
- [X] Removes extra allocation in campfire by using reverse loop.
- [X] Removes other LINQ calls that aren't needed.
