#667 JPG read problem - Invalid SOS parameters for sequential JPEG
It is interesting that other programs does not complain with this issue.
The latest gm compiled from sources converts JPG to BMP and only displays this error.
M:\temp>"D:\Program Files\GraphicsMagick-1.3.31-Q8\gm.exe" convert 20220721_1203
53_resized.jpg 20220721_120353_resized.bmp
D:\Program Files\GraphicsMagick-1.3.31-Q8\gm.exe convert: Invalid SOS parameters
for sequential JPEG (20220721_120353_resized.jpg).

As I recall, you updated libjpeg so you are using a different/newer
version than the release. Please take responsibility for this.

Previous version before my update is even much more worse. It does not convert provided JPG at all. I have found this issue in work when I atempted to convert JPG on stable gm from 2020. After my update of jpg library, the conversion is done.
This JPG has been created from Samsung Galaxy S3 mobile phone. I could try to even go step further and use newer JPG library.

I assume that it is not easy to support sequential JPEG, which is
really more like a video/movie. Supporting it properly would require
generating multiple frames like an animation.
