Subject: hibyOS: OF patcher script for Native ports

This is a script to patch a native bootloader
(bootloader.*) into a stock OF firmware image (update.upt).

Usage: hibyos_nativepatcher.sh <path/to/update.upt>
<path/to/bootloder.*>

Resulting file will be placed next to the original update, and will
be named [$orig_name]_patched_[$rbver].upt

Now with some rudimentary error checking at key points!

Works on macos.
Works on linux, at least debian in docker. Linux
usage requires 7z and genisoimage.
