Cleaned (kinda) npx-create-next-app including styled-components and react icons

This is the npx-create-next-app's output with some files removed and react-icons, styled-component included.

There is a GlobalStyle defined and used in pages/_app.js which you can use to apply your global styles using styled-components.

Also there is a Theme.js file which you could use to define colors, breakpoints and use them across the project
