altos: Optimize FEC encode and decode
Integrate interleaving, CRC and padding within the decode/encode
functions.
Provide for ISR priorities so that the 1120 RX interrupt takes
precedence over the other interrupts or we risk losing bits.
Optimize the viterbi decoder a bit (goes from 10ms per packet to 7ms
per packet).
