Combines tagged streams.
Takes N streams as input. Each stream is tagged with packet lengths. Packets are output sequentially from each input stream.
The output signal has a new length tag, which is the sum of all individual length tags. The old length tags are discarded.
All other tags are propagated as expected, i.e. they stay associated with the same input item.
