Currently it only supports userland-pwning chals. Kernel-pwning also need such a bootstrap.

• Add CLI parameter "-ker" to switch to kernel-pwn initialization
• Autodetection of bzImage file
• Extract vmlinux from bzImage, +tests
• "Unstrip" vmlinux like vmlinux-to-elf did, +tests
• Add templates for compress.sh/decompress.sh to work with cpio-compressed initramfs. Example [here]

• It is important for users to have vmlinux-to-elf and extract-vmlinux. Post-cargo installation script vs provide instructions in README.md.

Probably can add dependency on vmlinux-to-elf repo?
