Review Comment:
but I need to squeeze the `cast_to` in there, right? I didn't find a way how
to do that more elegantly
it's the same thing like the `let decimal_places: i32 =
decimal_places.try_into()` in the scalar case, except that we can't just
`try_into` since the type is dynamic in the arrow array
