Feature request: dyld macho --extract --create-symtab

[doronz88]

Reversing dylibs from the DSC can be tiresome. Each dylib references another, and without loading each one's dependencies you get an image with too many invalid pointers. I think ipsw could create a .symtab section where every extracted image has references to all the rest of the exported symbols from the other dylibs. That way, We could reverse only one image with all its required dependencies without loading each one individually.

If this works well, I'll also attempt writing an IDA plugin to load modules from the iOS 15 DSC based on ipsw.
