/**
 *
 * Implementation of the Signer interface that will allow signing operation from a Ledger Nano device
 *
 * @param transport A transport instance from LedgerJS libraries depending on the platform used (e.g. Web, Node)
 * @param path The ledger derivation path (default is "44'/1729'/0'/0'")
 * @param prompt Whether to prompt the ledger for public key (default is true)
 * @param derivationType The value which defines the curve to use (DerivationType.ED25519(default), DerivationType.SECP256K1, DerivationType.P256, DerivationType.BIP32_ED25519)
 *
 * @example
 * ```
 * import TransportNodeHid from "@ledgerhq/hw-transport-node-hid";
 * const transport = await TransportNodeHid.create();
 * const ledgerSigner = new LedgerSigner(transport, "44'/1729'/0'/0'", false, DerivationType.ED25519);
 * ```
 *
 * @example
 * ```
 * import TransportU2F from "@ledgerhq/hw-transport-u2f";
 * const transport = await TransportU2F.create();
 * const ledgerSigner = new LedgerSigner(transport, "44'/1729'/0'/0'", true, DerivationType.SECP256K1);
 * ```
 *
 * @example
 * ```
 * import TransportU2F from "@ledgerhq/hw-transport-u2f";
 * const transport = await TransportU2F.create();
 * const ledgerSigner = new LedgerSigner(transport, "44'/1729'/6'/0'", true, DerivationType.BIP32_ED25519);
