Peer deps preclude using React 17 without `--force` flag for `npm install`

[johnislarry]

Because the peer deps in this package target react@"^16.8.0", if your project uses react@17.0.2, then you get the following error when running npm install @react-chess/chessground.

I'm not sure if it was intentional to not support the most recent version of react, but I'm assuming (maybe incorrectly) that you wanted to support both 16.x and 17.x. If that's the case, you could use the || operator in the semver expression in your package.json like in this post: https://stackoverflow.com/questions/47309598/make-your-npm-package-support-multiple-versions-of-peer-depedency

Should be fixed as of version 1.2.1!
