Description

We don't perform enough checks on ArrayData when creating StringArray and LargeStringArray. As they use different integer sizes for offsets, this can create a problem where Offset<Vec<i32>> could be correctly reinterpreted as Offset<Vec<i64>> and vice versa.

We should add checks that pervent this. The same might apply for List and LargeList
