Unsafe World Random Access Detector

This is a mod that detects unsafe off-thread world random access, helping to find causes of "Accessing LegacyRandomSource from multiple threads" crash.

This is useful for finding the cause of mysterious crashes with Accessing LegacyRandomSource from multiple threads.
