Operation request: ECIES (Elliptic Curve Integrated Encryption Scheme libraries) encryption

## Summary
Please support ECIES (Elliptic Curve Integrated Encryption Scheme libraries) encryption, the official implementation of the address: https://github.com/ecies, which has a js implementation of the version, you can directly copy over.

```
### Example Output
#### ciphertext decrypted
```
THIS IS THE TEST
```

Start by reviewing the ECIES reference implementation linked in the issue and the repository's existing encryption operations. Confirm the supported scheme against the supplied private key, public key, ciphertext, and plaintext examples; done means the examples decrypt to "THIS IS THE TEST" and the operation is available in CyberChef.
