Progressive JPEG

[yuriolive]

Would be good if the JPG code also converts the JPEG images to progressive JPEG images.

There is a lot of advantages of using Progressive JPEG images instead of Baseline JPEGs.

It seems jpegoptim has an --all-progressive option http://manpages.ubuntu.com/manpages/bionic/man1/jpegoptim.1.html

Hello @yuriolive,
thanks for this very good suggestion. I will run tests with this option and if it work properly I will add it into the next release.
