General refactor: backend/frontend separation and API integration for ELF analysis

[giusbianco]

Pull Request Description

This pull request introduces a general refactor of the code, with a focus on improving the structure and clarity of the library through the following main interventions:

1. Separation between backend and frontend:

   • The code has been reorganised to clearly distinguish backend functionality (processing, application logic) from frontend functionality (user interface).
   • Names and structures follow a more intuitive convention to reflect their purpose and role within the library.

2. Integration of public APIs:

   • A practical example has been introduced, called behaviours-assessment, which uses the public APIs defined in the various library crates.
   • This example illustrates the use of the API to perform a static analysis of ELF binaries, showing how to integrate the main functionalities in a real context.

3. General improvements:

   • Refactoring of code to improve readability and maintainability.
   • Migration of functionality to favour a modular and reusable structure.
