Add debug log to createPersonGroup method

[Alevale]

Feature Request

Add a debug log when createPersonGroup is called to track when the method is invoked.

Proposed Change

Add the following line at the start of the createPersonGroup method in index.js:

createPersonGroup({ personGroupId = this.personGroupId, name, userData, recognitionModel = this.recognitionModel }) {
    console.debug('[FaceApiTranslator] createPersonGroup called', { personGroupId, name, recognitionModel })

    const stringifiedData = typeof userData === 'string' ? userData : JSON.stringify(userData)
    // ... rest of method
}

Why

To help with debugging and confirming that the tool has been called during development/testing.
