### Describe the usage question you have. Please include as many useful
details as possible.
It looks like `Array.unique` maintains the order of elements' appearance:
```python
In [30]: pa.array([1, 1, 2, 2, 1, 4, 2]).unique()
Out[30]:
<pyarrow.lib.Int64Array object at 0x7f48661a9900>
[
1,
2,
4
]
```
Is this guaranteed to always be the case? If so, would you be open to
documenting the guarantee?
