The plugin doesn't work if dangerfile is not transpiled

[mgol]

If you set the DANGER_DISABLE_TRANSPILATION environment variable to "true" to avoid transpilation, dangerfile.js is executed directly via Node.js. In that case, this plugin doesn't work as it only exposes transpiled sources which uses the regeneratorRuntime global that won't exist for untranspiled sources.

It'd help if you also exported untranspiled source in the npm package. Modern Node.js versions should understand it without any issues.
