Tailwind CSS compatibility release

This release is mostly a maintenance release. The only visible change is that thanks to #12 blocks.css now interoperates well with Tailwind CSS 🎉

Pills and Utils

This release rolls out two major updates to blocks.css:

• Thanks to @jajoosam, there are now .round blocks, which are pill-shaped:
  
• blocks.css now includes an experimental utility library, util.css, which is actually mostly here because I didn't want to create another NPM package. It includes common CSS classes to do things like spacing and layout, manage flexboxes, typography, and box shadows.

First release! 🚀

This is the first release of blocks.css. Check out the full documentation page for why this library exists, and how to use it on your page.
