Data race when using slicez.Shuffle and slicez.Sample concurrently

The rand changes in 96a84d8 is not concurrency safe, so if slicez.Shuffle or slicez.Sample is used concurrently, a data race may occur.
When operating directly on the rand package, a lockedSource is used internally to make the package methods concurrency safe, but rand.NewSource return a rand.Source that don't have any lock/mutex.

probably should start out with just a lock since rand/v2 is not available in older versions of go
