Major Description
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.
