CONVERT RGB/COMPLEX VOLUME TO FRAMES
   wb_command -volume-components-to-frames
      <input> - the RGB/complex-type volume
      <output> - output - the input volume converted to multiple frames of
         scalar type

      RGB and complex datatypes are not always well supported, this command
      allows separating them into standard subvolumes for better support.
