Appears in the NgModule.imports of AppRoutingModule, but could not be resolved to an NgModule class

Nobody has claimed this yet.

Tried to use `ngx-quicklink` with the angular 13 but the compilation is failing with the below logs. Any quick fix can help or let me know it’s a bug.

I'm using the latest version of `ngx-quicklink` with angular 13, which seems to not be compatible.

```sh
Error: node_modules/ngx-quicklink/src/quicklink-strategy.service.d.ts:4:22 - error NG6002: Appears in the NgModule.imports of AppRoutingModule, but could not be resolved to an NgModule class.

This likely means that the library (ngx-quicklink) which declares QuicklinkStrategy has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

Here is my `app-routing.module.ts`

```ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { QuicklinkStrategy } from 'ngx-quicklink';
import { ViewsModule } from './views/views.module';

const routes: Routes = [
{
path: '',
pathMatch: 'full',
redirectTo: 'home'
},
{
path: 'home',
loadChildren: () => import('./views/views.routing.module')
.then((m) => ViewsModule), data: {
shouldPreload: true
}
}
];

@NgModule({
imports: [
QuicklinkStrategy,
RouterModule.forRoot(routes, {preloadingStrategy: QuicklinkStrategy})
],
exports: [RouterModule]
})
export class AppRoutingModule { }

```

Here is the `app.modules.ts`

```ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { ComponentsModule } from './components/components.module';
import { ViewsModule } from './views/views.module';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AppRoutingModule,
ViewsModule,
ComponentsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

```

Any contribution is much aplicieted.

Start by reproducing the Angular 13 compilation failure from app-routing.module.ts, focusing on the QuicklinkStrategy import and the error in ngx-quicklink/src/quicklink-strategy.service.d.ts. Compare the library's Angular compatibility with the reported setup and verify that the Angular 13 build succeeds with the intended routing configuration.
