Add ability to use @babel/traverse using estree plugin, also fixes https://github.com/cherow/cherow/issues/273:

const babel = require('@babel/parser');
const traverse = require('@babel/traverse').default;

const source = `
    const t = ({a}) => a
`;

const babelAST = babel.parse(source, {
    plugins: [
       'estree', // with estree plugin @babel/traverse doesn't define variables
    ]
});

traverse(babelAST, {
    Identifier(path) {
        console.log('babel:', path.scope.hasBinding('a'));
        //outputs
        false
    }
});
