Introduces a new TTS provider using Google Cloud Text-to-Speech (Chirp HD model). This allows for higher quality and more natural-sounding voice synthesis.
The `TTSProviderCog` now includes:
- A `google_cloud_tts` option in the `_synthesize_speech` method.
- Checks for the `google-cloud-texttospeech` library and provides installation instructions if missing.
- Error handling for common Google Cloud TTS issues like quota limits or credential problems.
- A new choice in the `/ttsprovider` slash command for "Google Cloud TTS (Chirp HD)".
- A check for the availability of the `google.cloud.texttospeech` module on startup.
Introduce send_tenor_gif tool that uses AI to select the best GIF from Tenor search results and send it to the channel. Increase the default and maximum limits for Tenor GIF search tools to improve selection quality. Update parameter descriptions and validation accordingly.
Introduces `get_user_avatar_data` to retrieve a user's avatar as base64 encoded image data, allowing the AI to "see" the profile picture directly. This includes special handling in `process_requested_tools` to attach the image as a `types.Part` in the prompt.
Also adds `get_user_highest_role_color` to fetch the color and details of a user's highest-positioned role.
