A meta-stream for sending multiple streams down a single stream. Like mux-demux except in series instead of in parallel.
convoy-stream is useful in different cases to mux-demux for example,
replicating multiple files down a stream, or packing multiple files
into one file.
convoy-stream uses length packed frames, so binary data is also supported!
var convoy =var assert =var es =var c =var d =var c1 = c //push a stream onto the stack.c1c1//pipe the convoys together.cvar d1 = dd1
