[Feature Request] Dynamic style and quality for DALL-E 3 via prompt

[justinh-rahb]

🚀 Feature Request

Description:
Introduce a feature in our application that allows users to dynamically set the 'style' and 'quality' parameters for DALL-E 3 image generation at runtime through their prompts. This would be an enhancement over the current implementation, which uses global, static environment variables to set these parameters.

Problem Statement:
While our application currently supports setting DALL-E 3's 'style' and 'quality' parameters via environment variables, these settings are global and inflexible, applying uniformly to all images generated during a session. This setup limits the user's ability to tailor the style and quality of each image to their specific needs or preferences at the moment.

Proposed Solution:
Implement functionality where the application interprets specific hashtags within the user's text prompt (e.g., #natural, #vivid for style, and #standard, #hd for quality) and adjusts the 'style' and 'quality' parameters for that particular DALL-E 3 API call accordingly. The system should revert to the default values set by the environment variables if no relevant hashtags are detected in the prompt.

Benefits:
This feature would significantly enhance user experience by providing the flexibility to customize each image generation request. It would encourage creative experimentation with different styles and qualities, potentially leading to more engaging and diverse outputs. Furthermore, it adds an interactive element to the application, making it more responsive to user inputs.

Additional Context:
Given that users might not be familiar with the usage of these hashtags initially, it would be important to incorporate a user guide or help section explaining how to use these hashtags effectively. The feature should be designed to elegantly handle scenarios where users might input conflicting hashtags or invalid combinations.
