对于js文件会使用require引入

我的项目是中途换到ts的，所以项目里混合了js和ts，更新到新版本后，对于js导出的controller或service或用`import xx = require(xxx)`引入，但我的js代码里也统一使用了export default，导致获取引入的对象是一个`{ default: [controller|service] }`报错了，这个有办法配置解决吗？

Start by reproducing the mixed JavaScript/TypeScript case described in the issue, using a JavaScript default export with TypeScript's `import = require` form. Trace how egg-ts-helper handles the generated import and compare the runtime object with the expected controller or service; done means the default export is resolved correctly or the supported configuration is documented.
