Helpers for the Ledger Bitcoin application [WIP]

A transport implementing the ledger_hw trait is needed in most of the helpers.

example:

use bitcoin::util::bip32;
use ledger_hw_app_btc::get_wallet_public_key;
use ledger_hw_app_btc::AddressFormat;
use ledger_hw_transport_hid::HidTransport;
use std::str::FromStr;

#[tokio::main]
async fn main() {
    let transport = HidTransport::new().unwrap();
    let path = bip32::DerivationPath::from_str("m/44'/0'/0'/0/0").unwrap();
    let (pk, address, chaincode) = get_wallet_public_key(&transport, &path, true, AddressFormat::Legacy)
            .await
            .unwrap();
    println!("pk: {}", pk);
    println!("address: {}", address);
    println!("chaincode: {}", chaincode);
}
