Determinism for Serialization

[ZagButNoZig]

This a draft for making the serialization of a world deterministic by adding the necessary information to the serialization. It works by saving the free list and all the generations of all alive and de spawned entities.

TODOs

• [x] Fix the 2 serialize test cases
• [x] Remove column serialize from default features
• [x] Make sure everything works as intended
• [x] ~~Maybe add this to row serialization aswell~~ (Out of scope for this PR)
