ROADMAP: Moving PyAEDT Extensions to a separate repository

[Samuelopez-ansys]

The decision to move PyAEDT extensions to a dedicated repository introduces several key advantages for the development and maintenance of the project:

Focused Development: Separating extensions from the core PyAEDT codebase allows for targeted enhancements and updates to the extensions without impacting the primary functionality of PyAEDT.

Improved Modularity: A standalone repository enables better organization and a more modular structure, making it easier to manage and scale the extensions as independent components.

Simplified Maintenance: Issues related to extensions can be tracked and resolved within their own repository, leading to a more streamlined debugging and testing process.

Enhanced Collaboration: Contributors can work on extensions independently, fostering specialized development efforts and reducing complexity in the main PyAEDT repository.

Reusability and Versatility: A separate repository allows for the extensions to be reused in other projects or adapted for broader purposes outside of PyAEDT.

This move represents a strategic step toward improving the structure, maintainability, and scalability of the PyAEDT ecosystem.
