Safely Detecting 32bit & 64bit Systems

[DeLuks2006]

Since 32bit and 64bit headers have different offsets, we need a way to detect if the binary is 32bit and if so jump to another part in code that handles that

To fix, I'd use similar concepts as in Issue #2.

Or alternatively split the code from main.asm into more functions that take the "bitness" as argument and handle that internally.
