Converts a stream of bytes with 1 bit in the LSB to a byte with K relevant bits.
In other words, it packs K unpacked bits (one bit per byte, since the byte is the smallest item size in GNU Radio) into a single packed byte containing K bits and 8 - K zeros.
This block takes in K bytes at a time, and uses the least significant bit to form a new byte.
Example:
K = 4
in = [0,1,0,1, 0x81,0x00,0x00,0x00]
out = [0x05, 0x08]
