tool to inject a shell script into legacy shims

[redcathode]

Was working on a writeup on how to better mitigate the v114+ hardware write protect block, and ended up adding this to make things easier:

sudo ./wax/inject_preseed.sh -s <path/to/legacy_shim.bin> -p <path/to/preseed/file.sh>

It lets you modify the factory_install.sh of an injected legacy shim to source another shell script before the menu opens.
Still have a few things to do/test before merging, mostly:

• error out on modern and raw shims
• test WP check/unenroll script

you should really be using recomod for that
