Jonas Jenwald bf4166e6c9 Attempt to handle DNL (Define Number of Lines) markers when parsing JPEG images (issue 8614)
Please refer to the specification, found at https://www.w3.org/Graphics/JPEG/itu-t81.pdf#page=49

Given how the JPEG decoder is currently implemented, we need to know the value of the scanLines parameter (among others) *before* parsing of the SOS (Start of Scan) data begins.
Hence the best solution I could come up with here, is to re-parse the image in the *hopefully* rare case of JPEG images that include a DNL (Define Number of Lines) marker.

Fixes 8614.
