Let the user provide a Kernel image

[mischw]

Edit: Actually I might have found a way to access old Debian debug Kernels. Example: https://snapshot.debian.org/archive/debian/20231006T090846Z/pool/main/l/linux/
Not sure if something like that exists for Ubuntu and the others

---

Idea for a feature: Instead of providing the kernel number as string, let the user optionally provide a path to a already downloaded Debug Kernel. As someone mentioned in #4 the file cannot always be downloaded (Maybe they get removed when they are superseded? Any clues?) But sometimes they are still hosted on other sites (mirrors?) it seems. For example
I can still get the 6.1.0-13 Debug Kernel (linux-image-6.1.0-13-amd64-dbg_6.1.55-1_amd64.deb) from here
https://deb.sipwise.com/debian/pool/main/l/linux/
The us mirror seems to have it removed
http://ftp.us.debian.org/debian/pool/main/l/linux/

Thanks for your work! Nice project
