[FEATURE] add MIT License to project

[AndreaZentriegen]

Detailed description

Hi everyone,
As part of a university module on contributing to open-source projects, I explored this repository and noticed that the CONTRIBUTING.md file refers to the project’s open-source license. However, it seems that the license file is no longer present in the master branch.
To encourage collaboration and clarify usage rights, I’d like to suggest adding an MIT License. It’s a permissive license that allows others to use, modify, and share the code freely while ensuring proper attribution to the original authors.

Context

Having a license benefits the entire community. This allows you to verify the usage.
