Issue with dependencies
Hi there,

First, there are some really beautiful icons here - great work!

It looks like this package is accidentally including `react`, `react-dom` and other packages as dependencies, when those should be in `devDependencies` as they're not needed as a part of this package - but instead for the website.

Having multiple versions of `react` installed can cause issues ([example](https://reactjs.org/warnings/invalid-hook-call-warning.html)), which is how I found that `react` was bundled in this library.

Let me know if I can help resolve this!
