Saving/Loading

[sarkahn]

While it is a roguelike and permadeath is a thing, we should be able to a quit and resume a game in progress. Two options for saving

1 - Just use SerializeWorld. I've tested it and it actually works very well - it's fast and simple as long as we don't try to serialize the terminal (due to the hybrid component). The file size is a little large but compresses well. The biggest issue would be that "saves" between versions would likely be incompatible.

2 - Custom solution. Per entity serialization is possible as per this post from DreamingImLatios https://forum.unity.com/threads/serialization-how-to-iterate-over-all-components-of-a-given-entity.524553/#post-6735454:

var types = EntityManager.GetChunk(entity).Archetype.GetComponentTypes(Allocator.Temp);

From the ComponentType you can get the system type, which should open up plenty of approaches to tackle this.

Big downside here is...it would be really tedious to write!
