> Currently writableRequests are deserialized from network buffers into a bytearray based
datastructure (vertexIdData - ByteArrayVertexIdEdges, ByteArrayVertexIdMessages, etc.) and
then immediately stored into MessageStore, EdgeStore, etc. 
> In this diff we ensure that we can directly read from network buffers (while storing
in MessageStore for example) without creating an (unnecessary intermediate ByteArray based)
vertexIdData object.
