Support React 17

Current hookrouter doesn't support the react 17. Can you update the react version in package.json ?

Am downgrading react version to 16 in order to use hookrouter. Will you update the react version please?

I run hookrouter with React 17 by installing it using the --legacy-peer-deps flag and it works great.

npm install hookrouter --legacy-peer-deps

So it seems like it's already compatible. Just need to update the react dependency from "16.8.2" to ">=16.8.2".
