**Describe the bug**
<!--
A clear and concise description of what the bug is.
-->
If we have `None` as the first element in ListArray, it panics when we call
`cast_with_options`
**To Reproduce**
<!--
Steps to reproduce the behavior:
-->
```rust
#[test]
fn test_first_none_will_panic() {
//Panic
let array =
Arc::new(ListArray::from_iter_primitive::<Int64Type,_,_>(vec![None,
Some(vec![Some(1), Some(2), Some(3)])])) as ArrayRef;
let data_type =
DataType::FixedSizeList(FieldRef::new(Field::new("item", DataType::Int64,
true)), 3);
let opt = CastOptions::default();
let r = cast_with_options(&array, &data_type, &opt);
}
#[test]
fn test_non_first_none_pass() {
//Panic
let array =
Arc::new(ListArray::from_iter_primitive::<Int64Type,_,_>(vec![Some(vec![Some(1),
Some(2), Some(3)])])) as ArrayRef;
let data_type =
DataType::FixedSizeList(FieldRef::new(Field::new("item", DataType::Int64,
true)), 3);
let opt = CastOptions::default();
let r = cast_with_options(&array, &data_type, &opt);
}
```
**Expected behavior**
<!--
A clear and concise description of what you expected to happen.
-->
Should return correct casted array
**Additional context**
