Subject: fec: Adds MTU parameter to async and tagged stream blocks.
The maximum transmission unit (MTU, in bytes) sets up the encoders and
decoders with enough internal buffer space to accommodate frames of
varying sizes up to the MTU. Proections placed to make sure incoming
tagged streams and PDUs don't exceed this.
This also fixes a bug in the tagged stream encoder and decoder blocks
to properly use calculate_output_stream_length.
