Replace sha1 dependency with sha-1

[linkmauve]

This other crate is being maintained, and it offers better performances when using the asm feature (especially on AArch64).

Could you also update CHANGES.md?

Sorry again, could you rebase to make CI green?

[JohnTitor]

Ah, could you add a unit test to confirm that the output isn't changed?

like:

#[test]
fn test_hash_key() {
    let foo = hash_key("hello actix-web".as_bytes());
    assert_eq!(&foo, "cR1dlyUUJKp0s/Bel25u5TgvC3E=");
}

needs a test

[linkmauve]

Done.
