React 18 peer dependency

Having recently upgraded to React 18, I am receiving peerDependency warnings with regards to this package.

https://github.com/react-theming/theme-swatch/blob/master/package.json#L9

Are there any issues with modifying the peer dependencies to include React 18? 

`"react": "^16.8.6 || ^17.0.0" || ^18.0.0"`

Many thanks.
