Feature Request: Support for Additional ABAP Versions

## Feature Request: Enhance Compatibility with Older ABAP Versions

### Overview
The current README specifies that the Genie for SAP requires Google ABAP SDK version 1.9 or higher. To accommodate a wider range of users and systems, it would be beneficial to support earlier versions of the ABAP SDK as well.

### Proposed Solution
- Investigate the compatibility of Genie for SAP features with earlier versions of Google ABAP SDK.
- If feasible, provide backward compatibility by modifying the existing code or documenting the limitations.
- Update the README to reflect which versions of the ABAP SDK are supported and any specific requirements or limitations that come with earlier versions.

### Benefits
- This enhancement would allow more users to benefit from the AI-based features without the necessity of upgrading their systems, thereby increasing the user base and potential community contributions.

### Additional Notes
Please let me know if there are any technical constraints or considerations regarding this request. Thank you for your continued work on this project!
