Upgrade zune-jpeg

Currently targets 0.5.0-rc0, will switch to the full 0.5.0 release once it comes out

You need to use ZCursors rather than Cursor from what I can tell, did some testing and when decoding images with your implementation on an all black image and saw gray pixels randomly come up (they may have been new pixels), to look at an example of how I made it work (probably has some unnecessary code): main...Murad-Awad:image:upgrade-zune

I also tested out a version that is functionally the same as yours outside of setting the color + limits params properly (although limits is probably not needed at all given how it is initialized) + using ZCursor: main...Murad-Awad:image:mawad/keep-testing-zune

@Murad-Awad could you file an issue against the upstream zune-jpeg crate? My understanding is that this version without ZCursor is expected to decode JPEGs properly, so if you are seeing some that get corrupted, they'll want to know

will do!
