lndconnect: update to Zeus 0.7.1

- Generate lndconnect URLs with protocol `c-lightning-rest` for clightning.
  (Zeus now auto-detects the lightning implementation by the URL protocol.)
- Use improved QR code format (via qrencode)  .

5. Configure Zeus
- Add a new node

- For clightning: Set `Node interface` to `c-lightning-REST`
- Add a new node and scan the QR code
- Click `Save node config`
- Start sending and stacking sats privately
### Additional lndconnect features
- Create plain text URLs or QR code images
- Create a plain text URL:
```bash
lndconnect --url
lndconnect --image
```
- Set a custom host. By default, `lndconnect` detects the system's external IP and uses it as the host.
