   @tustvold not sure why the test fails on         
   ```
   Test casting Decimal128(38, 0) --> LargeList(Field { name: "item", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} })
   thread 'test_can_cast_types' panicked at 'called `Result::unwrap()` on an `Err` value: InvalidArgumentError("non-nullable child of type Utf8 contains nulls not present in parent LargeList(Field { name: \"item\", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} })")', arrow-data/src/data/mod.rs:1795:30
   ```
   
   Perhaps related to #3983
