What's your schedule to support progressive jpeg?

[PKUZHOU]

Thanks to your nice project. I notice that in your TODO list, you are going to support the progressive jpegs. May I ask when will you add the progressive jpeg feature? Thank you!

I think I could add support for the first ‘scan’ fairly easily, but full support maybe more tricky.
It’s not near the top of my list of things to do, tbh.
