React 17 Support with npm 8

[ajGingrich]

This currently works well with React 17 but it cannot be installed using npm 8 because the peer dependencies do not support React 17.

Solution: change the peer dependencies to the following.

  "peerDependencies": {
    "react": ">=16",
    "react-dom": ">=16"
  },

I can make this change if you'll accept a PR.

similar issue for me using preact 10, which I think is emulating react 18. Everything works fine, but I do get these warnings:

warning " > [email protected]" has incorrect peer dependency "react@^16.6.0".
warning " > [email protected]" has incorrect peer dependency "react-dom@^16.6.0".

This is a great package, and I will keep using it because it does what I want. But still would be nice to remove these warnings.
