ArrayAllocator (presto-common 0.278.1 API)

```
public interface ArrayAllocator
```
Manages the creation and return of primitive arrays, to be used within an operator to avoid repeated array allocation. Typically this will be used within BlockFlattener. The arrays which are returned may have a size which exceeds the specified positionCount, and they are not guaranteed to be filled with the type's default value.
