Event emitter for draw:canceled not available

[ma7moudat]

Similar to issue Leaflet/Leaflet.draw#1010, it would be nice to be have an event emitter for draw:canceled like all (or most) other events:

<div
    leaflet
    leafletDraw
    [leafletOptions]="leafletOptions"
    (leafletDrawCanceled)="onDrawCanceled($event)" <!-- we need this -->
>
...
</div>
