The first API/Package map contribution! Exciting!

Looks like the tests failed:

Assert.IsFalse failed. `Esri\Esri.ArcGISRuntime.Xamarin.Forms\esri.arcgisruntime.xamarin.forms.apimap.json' - ["Esri.ArcGISRuntime.ARToolkit.Forms"]["value"] cannot be empty.

That's on line 17 (the NotImplemented API). Let me poke Anton about that and see if perhaps my tests are wrong or what the value property should be in this case.

Already fixed - The doc made me think it should be empty, but I just removed the entry. Test passing for me. Rookie mistake not running those first

Excellent. I see you also fixed the other empty values. 👍
