Progressive JPEG support

[palmerabollo]

picojpeg does not support progressive JPEGs at the moment. I guess there are no plans to support it according to this comment https://github.com/richgel999/picojpeg/blob/master/picojpeg.c#L898-L899, am I right?

Progressive JPEG - not supported by picojpeg (would require too much memory, or too many IDCT's for embedded systems).

If that is the case, do you know other libraries that support decoding progressive JPEG images? I'd like to use something like this in a ESP32 but I wasn't able to find any. Do you know whether https://github.com/richgel999/jpeg-compressor supports it?

Thank you very much for your time creating these great libs, @richgel999.
