### Describe the bug, including details regarding any error messages,
version, and platform.
If I give a column of structs, then pyarrow seems to sort the fields by
name. I would expect the field order to be preserved.
```python
import pandas as pd
import pyarrow as pa
print(pa.__version__)
# 15.0.0
s = pd.Series([{"b": 2, "a": 1}, {"b": 4, "a": 3}])
a = pa.array(s)
print(a.type)
# struct<a: int64, b: int64>
```
