Multi-Shot Trigger (Mode 15)

Multi-Shot mode is a vendor-unique trigger mode that allows the user to fire a single hardware or software trigger
and have the camera acquire and stream a predetermined number of images.
The number of images to be acquired is determined by the parameter specified with the trigger mode. This allows
up to 255 images to be acquired from a single trigger. Setting the parameter to 0 results in a non-free running, non-
overlap mode. If Trigger Mode 14 is supported by the camera, setting the parameter to 0 results in a non-free
running, overlap mode.
Once the trigger is fired, the camera will acquire N images with an exposure time equal to the value defined by the
shutter, and stream the images to the host system at the current frame rate. Once this is complete, the camera
can be triggered again to repeat the sequence.
Any changes to the trigger control cause the current sequence to stop.

Note: During the capture of N images, provided that N>0, the
camera is still in an asynchronous trigger mode (essentially
Trigger Mode 14), rather than continuous (free-running) mode.
The result of this is that the frame rate is turned OFF, and the
camera put into extended shutter mode. Users should ensure
that the maximum shutter time is limited to 1/frame_rate to get
the N images captured at the current frame rate.
