> Original compression flow was like below:
> 1) Bundles messages in outgoing queue
> 2) Serializes bundle object to byte array
> 3) Compresses byte array to new byte array
> 4) Creates BSPCompressedBundle object for RPC communication
> So, it was extremely slow!
> Since BSPMessageBundle handles messages in byte array now, we can runtime compress the
messages during bundling. 
> We don't need BSPCompressedBundle class anymore.
