Mint with the Third Party Signer Guard

JavaScript

When minting via the Umi library, simply provide the third-party signer via the `signer` attribute like so.

```
create(umi, {
  // ...
  guards: {
    thirdPartySigner: some({ signer: myConfiguredSigner }),
  },
});
```

Remember to also sign the transaction with the myConfiguredSigner keypair.
