feat: Add support for Callout component

[YoussefHenna]

Hey. Great work on this package! It's really amazing and long overdue.

I'm part of the Draftbit team and this will be a great addition to our component selection. The one thing we needed that was missing was the Callout component. This PR adds that component + some changes to Marker to accommodate the Callout

Summary of changes

• Added Callout component
• Updated Marker to use default anchor (0.5,1)
• Updated Marker to support calloutAnchor prop
• Wrapped Marker in a class component to support showCallout and hideCallout
• Updated Marker to support Callout by passing down a context with callout specific data
• Updated docs 'supported list'

It looks good to me! Im glad to hear that you are using the lib for such an amazing project. Would you be interested in setting up some tests for the project? I'll open an issue to keep track of it.

Maybe at some point. Not in the next coming weeks though. Point me to the issue and I'll try to get to it in the near future.
