Remarks
This is different from ContinuousCaptureSession as it only returns a frame
from the native plugin when required. This is recommended for single-image
capturing or on-demand capturing where you don't need a continuous stream
of images.
Why does OnDemandCaptureSession inherit from ContinuousCaptureSession?
Because under the hood, both do the same thing - a repeating capture session. A true on-demand
capture results in a black image, so OnDemandCaptureSession runs a repeating capture
request running on an dummy texture natively, and reads the actual image through an ImageReader only
when requested to do so. This means that while the ContinuousCaptureSession processes
each and every frame sent to it, converting it to RGBA, OnDemandCaptureSession only
does it when required.
