Header not complex enough

[lawndoc]

I was trying to concatenate jaws code to the end of an elf binary for a CTF, but I ran into an issue where a false header was being picked up in the binary before it got to the actual jaws code.

To decrease the likelihood of this happening when injecting jaws into various files, I might need to consider making the header more complex/unique. The easiest way would just be to make it reasonably longer with additional spaces and tabs.

Definitely a breaking change, but jaws isn't that popular so it's not a huge deal... I'll be thinking about it.
