I'm trying to new `Cardano.Bip32PrivateKey` from string cborHex which in file `skey` generate by cardano-cli

```
import * as Cardano from "@emurgo/cardano-serialization-lib-nodejs";

function genAccountKey(cborHex: string) {
    return Cardano.Bip32PrivateKey.from_bytes(Buffer.from(cborHex, "hex"))
        .derive(harden(1852)) // purpose
        .derive(harden(1815)) // coin type
        .derive(harden(0)); // account #0

}
genAccountKey("58204022747367deee69f601900e15ddc04fc8024753b6a1539ee2a8bed29832f420");

```

but I got this err `(node:87994) UnhandledPromiseRejectionWarning: Invalid Secret Key size`
