explore (or flatten) RecordBatch with ListArray column (like Spark explode)

Hi

Does arrow-rs support exploding a ListArray in a column of a RecordBatch ?

eg.

RecordBatch{
col1: [0, 1],
col2: [["a", "b"], ["c]]
}

exploding would result in
RecordBatch{
col1: [0, 0, 1],
col2: ["a", "b", "c"]
}

Thanks,
Fabian

Adding Rust to the title in case people don't read all the way through.
