jscodeshift codemod that convert CommonJS(require/exports) to ES Modules(import/export) for JavaScript/TypeScript

• named export: module.exports.foo = foo & exports.foo = foo to export { foo }`
• named export: module.exports.bar = foo & exports.bar = foo to export { foo as bar }
• default export: module.exports = foo to export default foo
• ignore multiple module.exports = x

• const foo = require("mod") to import foo from "mod"
• const { foo } = require("mod") to import { foo } from "mod"
• const foo = require("mod").foo to import { foo } from "mod"
• const bar = require("mod").foo to import { foo as bar } from "mod"
• const o = { foo: require("foo") } to import foo from "mod"; const o = { foo }
