metadata.json missing from release

[nud]

Hi

While using ng-xi18n on an Angular2 project that uses ng-chartist, I get the following error:

Error: Unexpected value 'ChartistModule in <snap>/node_modules/ng-chartist/dist/chartist.component.d.ts...

Using regular builds through webpack works fine though, so it's just the ng-xi18n command that fails. Presumably other ng command-line tools might exhibit the same problems.

According to angular/angular#13240 the reason would be that metadata.json is missing from the release.

This module does not work with angular-cli aot builds due to a similar error:

ERROR in Unexpected value 'ChartistModule in .../node_modules/ng-chartist/dist/chartist.component.d.ts' imported by the module 'AppModule in .../src/app/app.module.ts'. Please add a @NgModule annotation.

I think it just needs the module annotations in the code. Maybe you can do the same thing with a metadata file but the standard way would be an annotation as far as I know.
