Would it make sense to override `next(int)` to always throw an exception? Even though it should not be possible for a user to call the method on the wrapper, it might be better to be on the safe side; for example in case a new `Random` method which depends on `next(int)` is added in the future (even though this is unlikely).

Suggestion:

     * Returns an instance of {@code Random} that delegates method calls to the {@link RandomGenerator}
