styled-icons/styled-icons v8.0.0 on GitHub

(breaking) renamed the Package icon in all icon packs to PackageIcon. If you previously had the following:
```
import {Package} from 'styled-icons/pack-name'
// or
import {Package} from 'styled-icons/pack-name/Package'
```
You will want to replace with:
```
import {PackageIcon} from 'styled-icons/pack-name'
// or
import {PackageIcon} from 'styled-icons/pack-name/PackageIcon'
```
This fixes an issue experienced where certain bundlers would, on case-insensitive file systems, try to load a package.json file instead of the icon source.
