1.0.1 _placeholder binary data isn't received correctly

[Curvel]

I am trying to use my Flutter client to receive byte data sent from my node.js server. The problem is that normal messages arrive, but byte data does not.

Trying to reproduce the behavior in the example app, I noticed that when I send from my server, the byte data is sent through a _placeholder and through a 2nd separate message.

1. message from node.js server
   451-[\"event.response\",{\"id\":\"81907ced-96df-49f5-91d3-4ace1659c658\",\"audioStream\":{\"_placeholder\":true,\"num\":0}}]
2. message from node.js server data = {Uint8List} size = 16606

This messages are received and can be debugged by this package. But are never emitted to the event listeners.

I tried debugging the code of this package but wasn't able to find a fix for it by now.

Maybe related to closed: #167
