Easy way to generate testing xprivs

xpriv.rs

use bip39::{Language, Mnemonic};
use bitcoin::{bip32::Xpriv, Network};

const MNEMONIC: &str = "bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon bacon";
fn main() {
    let mnemonic = Mnemonic::parse_in(Language::English, MNEMONIC).unwrap();
    println!("{}", mnemonic.to_string());
    let seed = mnemonic.to_seed("");
    let xpriv = Xpriv::new_master(Network::Regtest, &seed).unwrap();
    println!("{}", xpriv.to_string());
}
