Add equivalent to `Shuffle` function from `math/rand` and `math/rand/v2` packages, but based on randomness from `crypto/rand` package. This allows cryptographically secure shuffling of data. Also add `ShuffleSlice` function that shuffles a slice of any type. BREAKING CHANGE: Minimum required Go version is now 1.18 due the `ShuffleSlice` using generics.
