arrow-ord: Support sortting StructArray

[ParkMyCar]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Problem, I need to sort a StructArray and it doesn't seem to currently be possible.

Describe the solution you'd like

Ideally the arrow_ord::sort::sort(...) would support StructArray. pyarrow.StructArray supports this, so I believe it should be possible.

Describe alternatives you've considered

It doesn't seem like there are alternatives, it's just a missing API. Would love to hear though if there are ways to get a sorted StructArray!
