It is UNC <-> Ledger transport
Provides a set of commands that can be executed to communicate with UNC App installed on Ledger device:
* Read PublicKey from Ledger device by HD Path
* Sign a Transaction
## Examples
### Get PublicKey from Ledger
```rust
use unc_ledger::get_public_key;
use slip10::BIP32Path;
use std::str::FromStr;
let hd_path = BIP32Path::from_str("44'/397'/0'/0'/1'").unwrap();
let public_key = get_public_key(hd_path).unwrap();
println!("{:#?}", public_key);
```
#### Trick
To convert the answer into `unc_crypto::PublicKey` do:
```rust
let public_key = unc_crypto::PublicKey::ED25519(
unc_crypto::ED25519PublicKey::from(
public_key.to_bytes(),
)
);
```
### How to sign a transaction
```rust
use unc_ledger::{sign_transaction, SignTarget};
use unc_primitives::borsh::BorshSerialize;
use slip10::BIP32Path;
use std::str::FromStr;
let hd_path = BIP32Path::from_str("44'/397'/0'/0'/1'").unwrap();
let borsh_transaction = unc_unsigned_transaction.try_to_vec().unwrap();
let signature = sign_transaction(SignTarget::BorshUnsignedTx(borsh_transaction), hd_path).unwrap();
println!("{:#?}", signature);
```
#### Trick
To convert the answer into `unc_crypto::Signature` do:
```rust
let signature = unc_crypto::Signature::from_parts(unc_crypto::KeyType::ED25519, &signature)
.expect("Signature is not expected to fail on deserialization");
```
## Executable examples

```bash
RUST_LOG=info cargo run --example get_version
```
### Get PublicKey from Ledger
#### Display
```bash
RUST_LOG=info cargo run --example get_public_key_display
```
#### Silent
```bash

```bash
RUST_LOG=info cargo run --example get_wallet_id
```
### Sign a transaction
#### Transfer
```bash
RUST_LOG=info cargo run --example sign_transfer
```
#### Other
```bash
