I took a look at `ArrowColumnVector` in Spark and it seems to be using its
own nullability mechanism.
```
@Override
public UTF8String getUTF8String(int rowId) {
if (isNullAt(rowId)) return null;
return accessor.getUTF8String(rowId);
}
```
Given the performance impact, I am inclined to go ahead with this change.
