Usage

let seed = "000102030405060708090a0b0c0d0e0f";
let master_prv = ExtendedPrivateKey::from_seed_hex(seed).unwrap();

// xprv derivation
let xprv = master_prv.derive("m/0/1'/123'/456").unwrap();
let xprv_1 = xprv.to_base58();

let xprv = master_prv.derive_child(0).unwrap();
let xprv = xprv.derive_hardened_child(1).unwrap();
let xprv = xprv.derive_hardened_child(123).unwrap();
let xprv = xprv.derive_child(456).unwrap();
let xprv_2 = xprv.to_base58();

assert_eq!(xprv_1, xprv_2);

// xpub derivation
let xpub = ExtendedPublicKey::from_xprv(&xprv);

// base58
