README rework

I did a MAJOR readme overhaul by restructuring it into like one continuous story while also making it sound less like a research paper (although the research paper vibe was my goal at the start)

Before, my readme was messy with no structure and just mixed into each other

My cleanup was mainly just reordering it and changing a few paragraphs to sound less research-y and more fun/story vibe

Most of the info was already previously there from the first version of the readme so this session was just about presentation
