Add Web support

Support working react-native-calendar on web by using react-native-web

[nandorojo]

A few issues I'm facing on Web:

1. export { Calendar, CalendarProps } from './Calendar' should be changed to export type { CalendarProps } from './Calendar

Currently I'm seeing this issue:

For some reason, the JS module is exporting CalendarProps which doesn't exist. Not sure why that's happening, I haven't seen that before.

Similarly:

Attempted import error: 'SvgCircleProps' is not exported from './Circle'.

The module folder is exporting these TS types as JS variables.

3. After fixing those issues, I did get it to render on web. However, it doesn't actually let me swipe and the formatting is off:

react-native-gesture-handler works on web, so I'm not exactly sure why the gestures aren't.

Thanks for the web support goal!

@nandorojo Not bad, not bad 😸 Honestly, it looks even better than I was expected 🤣
Could you share your Web support, so I can run it and see the current state (with described bugs).

Yup, I installed it in my app and just ran the minimal example from the readme and gave it a black background. I would make a snack but they aren't adding reanimated 2 support until later this week.
