[kodxana]

Summary of Proposed Changes

This pull request introduces a series of changes to this fork implement a dual-licensing model under the MIT License and the GNU Affero General Public License (AGPL). The goal is to ensure the project's original work remains open and free under the MIT License, while modifications made by FurkanGozukara are protected under the AGPL to encourage contributions to remain open.

Changes Made

1. Added LICENSE_AGPL.md: A new license file has been added to clearly outline the terms under which modifications to the SUPIR project are licensed.

2. Updated README.md: The documentation has been updated to include a new section on licensing, detailing the dual-licensing model and providing links to both the MIT and AGPL license texts.

3. Reverted original LICENSE: Its required to include original license to comply with open source.

4. Source File Headers: All files edited by FurkanGozukara should have headers in modified source files to explicitly state the licensing under the AGPL. This is to clarify the distinction between original work and modifications.

Instructions for Using the Source File Header

For any new files created or existing files modified by FurkanGozukara (or other contributors in the future), the following header should be included at the top of each source file:
