Support for Web

Can we add the support for react-native-web.

Right now I'm using this workaround for the browser:

const is24HourFormat = () => !new Intl.DateTimeFormat([], { hour: 'numeric' }).format(0).match(/\s/);

Sorry for the late reply, I've been busy at work (... and forgot about this).

Browsers doesn't have the 12/24 hour settings-toggle mobile devices have (god I wish they had). So I'm not quite sure this request makes sense for this package (it should be fairly easy to wrap this package, and handle it for web?).

Also I'm not familiar with react-native-web, but PRs are always welcome.
