This looks like it is directly coming from quickraw:

quickraw-0.1.6/src/raw/renderer.rs:60:58:
not implemented

I think this should be reported upstream. If you want to be sure, I've made a repo here which you can fork and test in isolation:
https://github.com/woelper/dng-load-error

This seems to be a issue with quickraw. I'm guessing that it's due to an unsupported shooting mode, but it probably shouldn't flatout throw a panic and crash. Is this the same library that caused issues with dng being read as tiff? Because I'm able to reproduce that behaviour on the repo you linked with the file linked in the issue. I would suggest looking into rawloader to see if it can handle the majority of formats found in quickraw as a replacement (or maybe to be ran side-by-side and exclude those from quickraw which don't have complete support but do in rawloader) since quickraw doesn't seem to be maintained? At least actively that is. I'll report upstream and see if I can manage a reply as the maintainer doesn't seem to have been on GitHub in months.
