UI Improvements using rich

[Skazza94]

The existing CLI UI lacks certain features that would make it more informative, visually appealing, and user-friendly.

To address these shortcomings, we propose integrating the rich library into Kathará. The rich library provides a powerful set of tools for creating rich terminal-based user interfaces. By leveraging the capabilities of rich, we can introduce features such as enhanced text formatting, better tables, and more.

Moreover, this will remove some third party libraries (coloredlogs and terminaltables) that are used to achieve similar results, reducing the number of external dependencies.
