Review comment:
       This test fails as follows:
   
   ```
   ---- arrow::arrow_reader::tests::test_read_maps stdout ----
   thread 'arrow::arrow_reader::tests::test_read_maps' panicked at 'called `Result::unwrap()` on an `Err` value: InvalidArgumentError("Child type mismatch for Struct([Field { name: \"key\", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, Field { name: \"value\", data_type: Map(Field { name: \"key_value\", data_type: Struct([Field { name: \"key\", data_type: Int32, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, Field { name: \"value\", data_type: Boolean, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }]), nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, false), nullable: true, dict_id: 0, dict_is_ordered: false, metadata: None }]). Expected Map(Field { name: \"key_value\", data_type: Struct([Field { name: \"key\", data_type: Int32, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, Field { name: \"value\", data_type: Boolean, nullable: false, dict_id: 0, dict
 _is_ordered: false, metadata: None }]), nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, false) but child data had Map(Field { name: \"key_value\", data_type: Struct([Field { name: \"key\", data_type: Int32, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, Field { name: \"value\", data_type: Boolean, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }]), nullable: true, dict_id: 0, dict_is_ordered: false, metadata: None }, false)")', arrow/src/array/data.rs:308:34
   note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
   
   ```
   (the issue is the nullability of the child field is declared differently on the Struct's datatype than on the ArrayData)
