Bug fix: decrement bytes remaining in loop

Assets/Scenes/ARCollaborationData/TCPConnection.cs

                     int bytesRemaining = messageHeader.messageSize;
                     while (bytesRemaining > 0)
                     {
-                        m_ReadBuffer.Read(stream, 0, Mathf.Min(bytesRemaining, m_ReadBuffer.buffer.Length));
+                        bytesRemaining -= m_ReadBuffer.Read(stream, 0, Mathf.Min(bytesRemaining, m_ReadBuffer.bufferSize));
                     }
                     break;
             }
