Passing through errors from underlying streams

[DamonOehlman]

Been using multiplex for a while and loving it, but I'm not sure that stream error handling is well dealt with by the package. This hasn't been a problem before, but recently WebRTC data channels have been popping up edge cases that are giving my error handling a really solid run.

With some tinkering I found that modifying line 107 to the following code:

decode.pipe(through.obj(decoder)).on('error', dup.emit.bind(dup, 'error'))

the problem goes away but I'm not sure that is all that is required to ensure that unhandled errors in the local streams are bubbled up to a place in which they can be handled.

Any thoughts on what the right way to handle this is before I go all gangbusters with a PR?

Could you try v6.0.0 and see if that is still an issue? It uses a different wire protocol so make sure to update it on both ends
