Got replay working

Doesn't work across app runs, unlike handmade the crux here is raylib. Even if we did raylibs features ourselves there would still be an issue of restoring the gpu memory state. So in order to have replays work across app runs is proper state serialization.

I'll leave that for later and focus on the next core features.
