Adds Leaflet.Editable to Map component

[parksjr]

Allows for programmatic enabling of layer editing.

Example

const layers = featureGroup.getLayers();
layers.forEach((layer) => {
  layer.enableEdit();
  layer.on('editable:editing', (layer, leafletElement) => console.log('edit event'));
});

Leaflet.Editable for more documentation on usage.

Some background

We initially were going about the edit route via Leaflet.draw, until we ran into an issue similar to the one described here. Those comments led us to Leaflet.Editable, which was the easiest and cleanest solution for Sir FOGG.
