Review Comment:
```go
offsetType := arrow.PrimitiveTypes.Int32
err := concatListView(data, offsetType, out, mem)
```
I get an error when I do this. Maybe the cast is not even valid (?) in the
first place?
`cannot use offsetType (variable of type arrow.DataType) as
arrow.FixedWidthDataType value in argument to concatListView: arrow.DataType
does not implement arrow.FixedWidthDataType (missing method BitWidth)`
