fn main() {
    let mut file = File::open("SAVE.sav").expect("oopies");

    let mut data = Vec::new();
    file.read_to_end(&mut data)
        .expect("Failed to read test asset");

    let mut cursor = Cursor::new(data);

    let file = GvasFile::read(&mut cursor).expect("Failed to parse gvas file");
