MultiArch parsing non fat binary panicked with Scroll(BadOffset())

[messense]

Ideally it should return an Err instead of panicking?

[dependencies]
goblin = "0.3.1"

use goblin::mach::MultiArch;

fn main() {
    let fat = MultiArch::new(include_bytes!("thin_x86_64")).unwrap();   //  this returns Ok
    println!("{:?}", fat);  // panicked here
}

thin_x86_64 file thin_x86_64.zip

$ cargo run
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Scroll(BadOffset(8))', goblin-0.3.1/src/mach/mod.rs:413:45

OK, I think I should use Mach::parse instead of MultiArch::parse.

Ok but this is still really undesirable behavior panicking in the debug printer. Would be nice to change that unwrap to an unwra_or(“NO_ARCHES”) or something
