Palworld test are slow

[scottanderson]

It takes approximately 10s to run tests/palworld.rs on my machine. If possible, we should replace the file under test with a simpler example that doesn't take so long to run.

ZLib twice is taking most of the time. This file contains all the entities of a map (it's a world save).
Should be able to craft a smaller one from with all the possible data from a JSON representation of the file tho.
However for now, even a blank save generates a 700MB+ JSON file...

I have more complex saves that are almost 9GB when translated to JSON so editing them is nearly impossible as is.
