Angular 10 Ivy warnings

[brainydevs]

We can use the library just fine, it seems that upgrading to Angular 10 produces the following warning:

WARNING in C:\Dev\WebApp\src\NgApps\node_modules\ng2-img-tools\__ivy_ngcc__\dist\src\img-crop.service.js depends on 'rxjs/Subject'. CommonJS or AMD dependencies can cause optimization bailouts.
For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies

WARNING in C:\Dev\WebApp\src\NgApps\node_modules\rxjs\Subject.js depends on 'rxjs-compat/Subject'. CommonJS or AMD dependencies can cause optimization bailouts.

To replicate create new Angular 10 project, add ng2-img-tools and run ng serve.

Thanks.
