FIX - 814 - Clickable image on the cards

[sudeepto-dutta]

This Pull Request tries to solve the issue 816 by following the instructions given by @flyingcircle in this comment,

• I have added onPress and onLongPress props to <Image /> component.
• I have also made sure that <Component> inside the <Image /> component is set based on whether the user has passed either the onPress or onLongPress props or not. For inspiration, I have followed the <Avatar /> component.
• By doing the aforementioned changes, we can make use of imageProps prop in <Card /> component to pass onPress or onLongPress function props.
• Added appropriate types in the index.d.ts file.
• Added documentation in the image.md file for onPress and onLongPress props.

Let me know if any change is required in this Pull Request or not.

Thank You.
