Google Chrome blocks due to CORS policy.
When working in Chrome, using the web components installed with `npm install boxicons` doesn't yield anything, due to the Cross-Origin Resource Sharing policy. This was the console error:

```
Access to XMLHttpRequest at 'http://unpkg.com/boxicons@2.0.2/svg/regular/bx-loader.svg' from origin 'http://localhost:5000' has been blocked by CORS policy: The response is invalid.
```

Do you know how I can fix this? I am using Flask and React as well, but I wouldn't think those would have any impact.
