* \brief Convert a stream of unpacked bytes or shorts into a stream of packed bytes or
* shorts. \ingroup byte_operators_blk
*
* \details
* input: stream of T; output: stream of T
*
* This is the inverse of gr::blocks::packed_to_unpacked_XX.
*
* The low \p bits_per_chunk bits are extracted from each input
* byte or short. These bits are then packed densely into the
* output bytes or shorts, such that all 8 or 16 bits of the
* output bytes or shorts are filled with valid input bits. 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.
