public static EncodedClusterStateBundle fromCompressionBuffer(Compressor.Compression compression) {
        return new EncodedClusterStateBundle(compression);
    }
Contains an opaque encoded (possibly compressed) representation of a ClusterStateBundle.

This bundle can in turn be sent over the wire or serialized by ensuring that all components
of the Compressor.Compression state can be reconstructed by the receiver. In practice this
means sending the Compression's <em>type</em>, <em>uncompressedSize</em> and <em>data</em>.
