> At the moment, we only support lists with a variable size per entry. In some
> cases, each entry of a list column will have the same number of elements. In
> this case, we can use a more effective data structure as well as do certain
> optimisations on the operations of this type. To implement this type:
> * Describe the memory structure of it in Layout.md
> * Add the type to the enums in the C++ code
> * Add FixedSizeListArray, FixedSizeListType and FixedSizeListBuilder classes
> to the C++ library
