Remarks
Get a list of the postview sizes supported for a still capture, using its capture size captureSize, to use as an output for the postview request.
Available postview sizes will always be either equal to or less than the still capture size. When choosing the most applicable postview size for a usecase, it should be noted that lower resolution postviews will generally be available more quickly than larger resolution postviews. For example, when choosing a size for an optimized postview that will be displayed as a placeholder while the final image is processed, the resolution closest to the preview size may be most suitable.
Note that device-specific extensions are allowed to support only a subset of the camera resolutions advertised by StreamConfigurationMap#getOutputSizes.
