Inconsistent order of `impl_proxy`

I just noticed a very weird thing: inconsistent order of impl_proxy:

I take a look at device.rs and util.rs, and I assume the order should be u8 u16 u32 u64. But I don't know what lead to the weird result.

// util.rs
pub fn get_register_sizes(d: &Device) -> Vec<u32> {
    let mut reg_sizes = HashSet::new();
    for p in &d.peripherals {
        for r in p.all_registers() {
            if let Some(size) = r.properties.size {
                reg_sizes.insert(size);
            }
        }
    }
    let mut reg_sizes: Vec<_> = reg_sizes.into_iter().collect();
    reg_sizes.sort();
    reg_sizes
}

// device.rs
let reg_sizes = util::get_register_sizes(d);
let generic_file = std::str::from_utf8(include_bytes!("generic.rs"))?;
if config.generic_mod {
    let mut file = File::create(config.output_dir.join("generic.rs"))?;
    writeln!(file, "{}", generic_file)?;
    for ty in reg_sizes {
        writeln!(file, "impl_proxy!({});", ty.size_to_str()?)?;
    }
