probe: Allow providing compressed image as ‘progressive jpeg’

[hv0905]

Now we have supported compress an image by width and height provided. However, it might still takes a long time to load the image sample through a slow network. This is unavoidable, but if we support compress the image as progressive jpeg, the user experience might be better.

Or use webp might be better.

Nice one. I will investigate it.
