README improvements

Some possible improvements for the README.md:

• Use Cases: Might be good to briefly mention some specific problems Lume can solve or scenarios where it can be beneficial to use Lume.
• Quick Example: While you have information about how to install and import Lume, a quick code example to demonstrate the simplest use-case would help users quickly understand its utility - maybe a reference to using the alluvial? Screenshots/GIFs could be more effective than text here in general given it's a data visualization library.
• Features: List the features that make Lume stand out, or any features you plan to add in the future, to give users an idea of why they might choose it over other similar libraries.
• FAQs: You might want to include a Frequently Asked Questions section to anticipate and resolve common issues that users might face.

Thanks @jrodriguez5909 for the pointers
