/**
* Quirk required to turn on/off HDR+ on Pixel devices by enabling/disabling zero-shutter-lag
* (ZSL) mode on the capture request, depending on the image capture use case's capture mode, i.e.
* prioritizing image capture latency over quality, or vice versa. This means that when the
* capture mode is {@link ImageCapture#CAPTURE_MODE_MINIMIZE_LATENCY}, HDR+ is turned off by
* disabling ZSL, and when it is {@link ImageCapture#CAPTURE_MODE_MAXIMIZE_QUALITY}, HDR+ is
* turned on by enabling ZSL.
