Breaking changes when porting to v1.0.0

react-otp-input is now a controlled component to facilitate functionalities that weren't possible before from the application using it, such as clearing or pre-assigning values. For v1.0.0 and above, a value prop needs to be passed in the component for it to function as expected.
