feat: add async methods to CRUD operations

Closes #23

Thanks @jordanpowell88! Nice job!!

Looking through this a couple things to come to mind, what do you all think about wrapping the non-async functions and reusing them as opposed to redefining the existing logic?

So for example:

getAllAsync would become:

public getAllAsync(): Observable<T[]> {
    return of(this.getAll());
}

See comment about typing the return type.

I echo @wesleygrimes comment as well. Helps to centralize the logic.

Agreed on wrapping the methods. Don’t know why I didn’t think of that originally :facepalm

It's ok, I would have done the same thing

[wesleygrimes]

Almost, just a couple tweaks.
