Asynchronous saving to reduce save lag

[Fornax]

I realize this would be a very significant change (definitely on the game engine side), but it might still be worth suggesting - would it be possible to implement asynchronous saving in DST?

From my understanding implementing async saving with the fork() syscall on both Unix-based systems would greatly reduce save lag. This would allow the main game to keep running smoothly while the save process is handled by a separate child process, minimizing interruptions.

I imagine that the majority of dedicated servers run on Linux, making this especially beneficial. This would of course be a qol improvement for Linux desktop and macOS users as well. Of course fork() isn't available on Windows.

IIRC Factorio has been using async game saves for a long time.
