docs(README.md): added bit components (#152)

Exported library using bit so people can now:
- Find and install the component in bit.dev.
- Play with the examples and edit the code.
- See all the tests in each component.
- Install each component individually instead of installing all the project.
- Import component in their project to modify the code locally if needed.
- See all dependencies.
- See bundle size of the component before installing it.
