update package to hooks

[chescalante]

Hi @shahnawaz, I'm sending you this pull request with changes for adapting the package for hooks.

Highlights:

1. Component props are now deconstructed in the component function definition. I believe this way is more readable and easy to change.
2. defaultProps it is now removed, it can be placed directly when the props are deconstructed. Same benefits as in 1.
3. I took componentDidMount, componentWillUnmount, _startLineAnimation and _animateLoop and replaced it with useEffect: allowing start and re-start an animation when parameters change or when the component is mounted.

Let me know what you think
