by default crate linked as shared library

with:

//cat src/main.rs
use secded::SecDed64;
use secded::SecDedCodec;

fn main() {
    let secded = SecDed64::new(56);
    println!("code_size {}", secded.code_size());
    let before: [u8; 8] = [255, 255, 255, 255, 255, 255, 255, 0];
    let mut buf: [u8; 8] = before;
    secded.encode(&mut buf);
    secded.decode(&mut buf).unwrap();
    assert_eq!(before, buf);
}

#cat Cargo.toml
[package]
name = "foo"
version = "0.1.0"
authors = ["Evgeniy A. Dushistov <dushistov@mail.ru>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
secded = "1.0.1"

$ ldd target/debug/foo | grep secded
        libsecded-07bbedaae9031f98.so => not found

so the create is not builtin, it used as shared library, this make deploy quite complex.
