Remove External Dependencies on Scramble and Objcopy

Added Ability to Scramble and Convert Bin to ELF without calling external binaries. Tested working on both MacOS(arm)+Linux.

There's also a few small changes to get it to compile on MacOS as that's the machine I was using this weekend. There's no elf.h file included with a vanilla install so I added a simple one with the required pieces to decode an elf for ease of building. I made a recipe for brew to install libisofs which I'm hoping to get upstreamed and then I'll add some build instructions for MacOS.
