Subject: fec: wip: adding concept of padding for CC encoder/decoder.
When using terminated mode, the CC encoder adds K-1 bits to the output, which doesn't fit a full byte and will throw off the book-keeping in PDU or tagged mode. Padding to fill a byte tells both encoder and decoder to handle the extra bits.
