Add Dual Licensing: AGPL for Code

[maehr]

Describe what feature you'd like. Pseudo-code, mockups, or screenshots of similar solutions are encouraged!

Background

The project currently uses a CC BY 4.0 license, which is excellent for data and documentation. However, for the codebase, a more appropriate license like AGPL could provide better protection and clarity.

Suggested Changes

1. Add a new LICENSE-AGPL file in the root directory, specifying that the code is licensed under AGPL.
2. Update the README.md to mention the dual licensing strategy.
3. Update any headers in source code files to reflect the dual license.

Benefits

• AGPL offers better protection against proprietary use of the code.
• Dual licensing provides clarity on how different project components can be used.

Tasks

• Add LICENSE-AGPL with AGPL text.
• Update README.md.
• Update source code headers.
