Progressive Reply
Some commands send replies progressively, as multiple messages. This allows the sensor to stream data
without buffering it first, and allows the client to obtain progress information on the stream.
A progressive reply begins with an initial, standard reply message. If the status field of the reply indicates
success, the reply is followed by a series of “continue” reply messages.
A continue reply message contains a block of data of variable size, as well as status and progress
information. The series of continue messages is ended by either an error, or a continue message
containing 0 bytes of data.
