The attr `block_size` indicates the input block size and how the data is moved.

  * Chunks of data of size `block_size * block_size` from depth are rearranged
    into non-overlapping blocks of size `block_size x block_size`
  * The width of the output tensor is `input_depth * block_size`, whereas the
    height is `input_height * block_size`.
