Open source licenses

References #342 (closed)

1. Developed a comprehensive list of all model dependencies and their respective licenses.
2. Created scripts to generate a distribution pie chart.
3. Organized these files in a dedicated folder (open-source-licenses) which includes:
   • README.md: Contains the list of dependencies and licenses, distribution pie chart, and license descriptions.
   • generate_pie_chart.py: Script to generate the distribution pie chart.

Additionally, a reference to this dedicated folder and its contents has been added to the main README.md file.

Please note that it's important to keep this list up-to-date whenever there are updates to the pip dependencies. The script provided will facilitate this process.

Final note: all the dependencies are compliant with Apache 2.0 License.
