Target Feature Group (+ Additional Events)

[QbDesu]

I would like to be able to have FreeDraw put the polygon layers on a specific layer/feature group because as of now it is hard-coded to add them to the map directly.
https://github.com/Wildhoney/Leaflet.FreeDraw/blob/master/src/helpers/Polygon.js#L73-L75

const polygon = new Polygon(latLngs, {
    ...defaultOptions, ...options, className: 'leaflet-polygon'
}).addTo(map);

It would be way nicer to handle that way.

Also a simple events like freeDraw.on("drawcommit", e => console.log(e.layer)) would be nice.
The events I would like to see are:

• drawstart - self-explanatory I think, maybe include the start latlng
• drawend - triggered whenever drawing is stopped, contain recorded latlngs
• drawcancel - triggered whenever drawing is canceled, contain recorded latlngs
• drawcommit - triggered whenever drawing is canceled, contain recorded latlngs, ALSO contain the newly created polygon layer if available(!)
• editstart, editend, editcancel(?), editcommit

Maybe also have an option to not submit the drawn area when the mouse leaves the map but instead cancel or do nothing.

I would also do it but I would rather have you do it because I hardly know anything about the project and would rather not have to learn all the details to do it. The most important part to me is the target feature group.
