Convert a stream of unpacked bytes or shorts into a stream of packed bytes or shorts.

Convert a stream of unpacked bytes or shorts into a stream of packed bytes or shorts.
input: stream of unsigned char; output: stream of unsigned char
This is the inverse of gr_packed_to_unpacked_XX.
The low 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_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.
