Construct a HTTPTimeSeekResponse with time and byte range
start_time and start_byte must be specified.
if total_duration and total_size are UNSPECIFIED, then the content duration/size will be signaled as unknown ("*")
if end_time is UNSPECIFIED, then the time range end will be omitted from the response. If the end_byte is UNSPECIFIED, the entire byte range response will be omitted. (see DLNA 7.5.4.3.2.24.3)
