Add Image Generation Capabilities to Nevron

[gromdimon]

Description

We need to add image generation capabilities to Nevron, enabling the agent to create images based on user prompts. This feature will support multiple image generation providers, ensuring flexibility and adaptability.

The feature should:

1. Allow users to generate images via API requests.
2. Support multiple providers (e.g., OpenAI’s DALL·E, BlackForestLabs' FLUX).
3. Allow users to specify image parameters (resolution, style, format, etc.).
4. Return image URLs or raw image data for further processing.

Requirements

1. Supported Image Generation Providers

• DALL·E (OpenAI) – Simple API-based image generation.
• FLUX (BlackForestLabs API) – Open-source alternative, possibly faster for specific use cases.

3. Configuration & Customization

• Allow users to configure API keys for external providers via .env.
• Enable switching between different providers dynamically.
• Support different image styles and resolutions.
• Add safety filters to prevent inappropriate content.

4. (Optional) Image Processing & Post-Processing

• Enable upscaling for higher image quality.
• Support style customization (e.g., photorealistic, anime, sketch).
• Allow batch generation to create multiple variations of an image.

Implementation Steps

• Integrate DALL·E via OpenAI API.
• Integrate FLUX via BlackForestLabs API.
• Implement provider switching logic.
• test

Expected Outcome

This feature will allow Nevron to generate high-quality images dynamically, enhancing its capabilities for content
