> Implement a DeleteFilter that changes an Iterable of VectorizedRowBatches in a way that whenever a new batch is seen in the {{next()}} method, we iterate its rows and apply the original Iceberg DeleteFilter on it. In VRBs we can utilize the {{selected}} array to mark rows as selected (not deleted), so essentially we're going to implement the {{markRowDeleted}} method.
