vocoder: allow input & output rates to differ
The input & output rates of the FreeDV modulator aren't necessarily the
same. In particular, the 2400A and 2400B modes have an input rate of
8000 sps and an output rate of 48000 sps. To allow for arbitrary input &
output rates, I've changed freedv_tx_ss from sync_block to block.
