Update Command-line Interface (CLI)

[enpuyou]

Context and feature:
The command-line interface has not been updated since the early stage of the project. Since then, more analysis has been implemented and displayed on the web interface, namely, streamlit, but not on the CLI. It is worth discussing whether or not the CLI should still be part of the project. If not, then perhaps the section of CLI in the documentation should be removed with the file textmining.py so that it would not be misleading for potential users; otherwise, the CLI should be updated with most of the web interface features. Suggestions and discussions are greatly appreciated.
