iBootim image support

[HappyMac3920]

One of my favorite things I like to do when I tinker around the iOS filesystem is extracting the firmware images (like Apple logo, recovery screen etc.) from the ipsw. There is already a tool for that named iBootim (https://github.com/realnp/ibootim), but it is only for Intel based Macs (there are forks and other build options for Apple Silicon Macs, but it is not on the original one) and is not designed to be built for Linux or Windows. It would make life easier if there was an ipsw ibootim tool that would work across platforms.
