Review comment:
We had a similar discussion on DataFusion for `RecordBatch` a while
back. We now just refuse duplicated column names, as it offers a much, much
simpler way of dealing with columns via column names.
However, sometimes people have to parse files with equal column names, which
means that arrow somehow has to support them on `RecordBatch`.
