Rename deprecated React lifecycle names to their UNSAFE_ equivalents in class components, object literals, and member references.

Usage

Before

 1  const React = require('React');

 3  class Component extends React.Component {
 4    componentWillMount() {
 5      this.componentWillReceiveProps(this.props);
 6    }
 7    componentWillReceiveProps() {}
 8    render() {

This is one example from the codemod's test cases. The codemod may handle many more cases.
