Verify a token submitted by a user:

```typescript
import { verifyHcaptchaToken } from 'verify-hcaptcha';

const result = await verifyHcaptchaToken({
    token: "USER-SUBMITTED-RESPONSE-TOKEN",
    secretKey: "YOUR-SECRET-KEY",
    siteKey: "YOUR-SITE-KEY",
});

if (result.success) {

} else {
    console.log("User is robot");
