<p>When QR Codes use multiple data blocks, they are actually interleaved.
That is, the first byte of data block 1 to n is written, then the second bytes, and so on. This
method will separate the data into original blocks.</p>

@param rawCodewords bytes as read directly from the QR Code
@param version version of the QR Code
@param ecLevel error-correction level of the QR Code
@return DataBlocks containing original bytes, "de-interleaved" from representation in the
        QR Code
