Code from example directory panics for Rufus executable on Windows

[3nthusia5t]

https://github.com/pbatard/rufus/releases/download/v4.4/rufus-4.4.exe

I have tried to run the example code against the rufus-4.4.exe on Windows operating system. The code panicks on the line

let icon_file = dir.to_icon_buffer(&pe).unwrap();

Writing 120.ico

The code which I run is available in repo:

use exe::*;

    let pe = VecPE::from_disk_file("rufus-4.4.exe").unwrap();
    let rsrc = ResourceDirectory::parse(&pe).unwrap();

    for (id, dir) in &icons {

            ResolvedDirectoryID::Name(name) => format!("{}.ico", name),
        };

        println!("Writing {}", filename);

        let icon_file = dir.to_icon_buffer(&pe).unwrap();
        icon_file.save(filename).unwrap();
    }

    println!("Icons dumped from executable");
