Request the start of an image stream.

This message dictates the form of the [ImageReply](structensightservice_1_1_image_reply.xhtml "An image frame message.") messages. One can have the images flipped vertically and can optionally chunk an entire image frame into multiple [ImageReply](structensightservice_1_1_image_reply.xhtml "An image frame message.") messages. Empirical measurements demonstrate that gRPC can transfer smaller blocks of pixels faster that larger blocks. If the chunk option is enabled, the [ImageReply](structensightservice_1_1_image_reply.xhtml "An image frame message.") messages will contain 1MB of pixel data maximum. The client must concatenate the pixel data from consecutive [ImageReply](structensightservice_1_1_image_reply.xhtml "An image frame message.") messages until it receives a message with the final flag set. At that point, all of the pixel data for a complete image frame has been received.
