## `random_ordered_range` not accessible from the `more_itertools` module

The new `random_ordered_range` function is not accessible through the `more_itertools` module, even though it was recently added. Trying to use it raises an `AttributeError`.

### Reproduction

```python
import more_itertools as mi

# Trying to use random_ordered_range raises AttributeError
result = sorted(mi.random_ordered_range(10))
print(result)
```

This raises:
```
AttributeError: module 'more_itertools' has no attribute 'random_ordered_range'
```

The same error occurs for all valid call signatures, e.g.:

```python
mi.random_ordered_range(100, 200)      # two-arg form
mi.random_ordered_range(1000, 2000, 10)  # three-arg form
set(tuple(mi.random_ordered_range(6)) for _ in range(10**5))  # permutation coverage check
```

### Expected behavior

`random_ordered_range` should be accessible as `mi.random_ordered_range` and should behave like `range` in terms of which values it produces, but yield them in a randomly shuffled order. For example, `sorted(mi.random_ordered_range(10))` should equal `list(range(10))`, and calling it many times with a small argument like `6` should eventually produce all `6! = 720` distinct permutations.

### Actual behavior

Accessing `mi.random_ordered_range` raises `AttributeError: module 'more_itertools' has no attribute 'random_ordered_range'`, indicating the function is not exported from the package's public namespace. The function needs to be added to the package's `__init__.py` (or equivalent export mechanism) so it is importable at the top level.
