merge the loading systems

this will probably fix #32 in the process, as it should take care of how the loaded entities are gonna live in the world

• clear existing entities before load

do you need to? can't you query for added dynamic instance (would help with the fact that it's async) and so whenever there's an entity with dynamic instance, it processes all the children of it and then despawns it

i think you can query for <(Entity, Text), Without<Anchor>> and regenerate (loop that query separately) and also rename to holes
