Update `react` peer dependency to `>=16.0.0` (#36)
Update `react` peer dependency to `>=16.0.0` (#36)

Currently, `react` is listed as peer dependency versioned at `>=16.0.0-alpha.12 <17.0.0`.  This version is overly restrictive.  I can confirm this project works in an environment with react >17. 

That particular version precludes projects from using this package in more modern react-native environments that requires `react`: `>=17.0.0`.

This problem becomes particularly apparent if using npm >= 7.     npm7  now errors if there are conflicting peer dependencies installed.

I am proposing simply removing the upper bound for the `react` peer dependency so users can `npm install` without error and continue to use this package in modern react-native environments!
