* Always represent TransportableObject internally as a single array of bytes. Various properties, such as `header`, or `object_string`, decode various segments of the byte array. * Store the serialized object as raw picklebytes without base64-encoding. As a result, `get_deserialized()` no longer needs to create a temporary copy of the raw picklebytes. The data segment is directly unpickled. Base64-encoding is applied to the data segment or the entire internal buffer whenever a print friendly representation of the `TransportableObject` is desired. * Since the properties of `TransportableObject` are simply views into the underlying buffer, `TransportableObject` may itself be serialized efficiently by simply writing out the byte array. ` Add backward compatibility layer for deserialization

Always represent TransportableObject internally as a single array of bytes. Various properties, such as
header, orobject_string, decode various segments of the byte array. This allowsTransportableObjectto be serialized efficiently by simply writing out the byte array.Store the serialized object as raw picklebytes without base64-encoding. As a result,
get_deserialized()no longer needs to create a temporary copy of the raw picklebytes. The data segment is directly unpickled. Base64-encoding is applied to the data segment or the entire internal buffer whenever a print friendly representation of theTransportableObjectis desired. A backward compatibility layer is introduced to automatically handleTransportableObjects serialized in the earlier format.
