Error handling errors

RustRAT uses libffi (more specifically the libffi-rs bindings) to call arbitrary functions at run-time. This works by putting the function’s argument and return types into a struct and providing libffi with a function pointer. Libffi then makes sure that all the arguments are placed in the correct registers or on the stack and calls the function pointer. I am not that proficient with Rust yet, but if anything is unsafe, I am pretty sure this is it.
