Implement capturing an image as PNG
I've got this sensor in my HP envy x360 15 model from 2021 and decided to play around a bit.
I don't have a windows installation to get USB traces, so I had a look at the driver and found a way (three different ones, actually, this one is to grab an image immediately) to get a raw 14bit image from the sensor.
Taking it a step further, with a quick-n-dirty PyQt GUI it's visible that it can capture at about 6-7fps, which is fun.
