Read and generate parquet array column.
When D=1, R=0, representing an empty array. Empty array is not a null value, so the NullMap for this row is false,
the offset for this row is [offset_start, offset_end) whose `offset_start == offset_end`,
and offset_end is the start offset of the next row, so there is no value in the nested primitive column.
When D=0, R=0, representing a null array, and the NullMap for this row is true.
