feat: Support loader function as input for route component

[brandonroberts]

Loaders can be used to fetch data for the component, run checks such as auth, redirect, and more.

import { Component } from '@angular/core';

@Component({
 template: `
 <router>
 <route path="/lazy"
 [load]="components.lazy"
 [loader]="() => Promise<Response> | Observable<Response>">
 </route>
 </router>
 `,
})
export class MyComponent {
 data$: Observable<Data> = getLoaderData();

 constructor(private loaderData$: LoaderData) {}

 components = {
 lazy: () => import('./lazy/lazy.component')
 };
}

@brandonroberts I am looking to familiarize myself with the inner working of this project, would you mind if I took a crack at this.

[brandonroberts]

Cool @mainawycliffe. You're welcome to, but I wouldn't put too much effort into it at the moment. I'm still evaluating this vs alternative options for routing

@brandonroberts Thanks. That looks interesting, will take a look while I get a chance. If it's what I think it is, I am really looking forward to it.
