> If the input data is a byte array, we should allow TorrentBroadcast to skip serializing and compressing the input.
> To do this, we should add a new parameter (shortCircuitByteArray) to TorrentBroadcast, and then avoid serialization in if the input is byte array and shortCircuitByteArray is true.
> We should then also do compression in task serialization itself instead of doing it in TorrentBroadcast.
