* \brief Convert a stream of packed bytes or shorts to stream of unpacked bytes or
* shorts. \ingroup byte_operators_blk
*
* \details
* input: stream of T; output: stream of T
*
* This is the inverse of gr::blocks::unpacked_to_packed_XX.
*
* The bits in the bytes or shorts input stream are grouped into
* chunks of \p bits_per_chunk bits and each resulting chunk is
* written right- justified to the output stream of bytes or
* shorts. All b or 16 bits of the each input bytes or short are
* processed. The right thing is done if bits_per_chunk is not a
* power of two.
*
* The combination of gr::blocks::packed_to_unpacked_XX_ followed by
* gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the
* general case of mapping from a stream of bytes or shorts into
* arbitrary float or complex symbols.
