Access freedraw directly

If you need to access the freeDraw Object directly : you can do it with a ref on the markercluster vue element and using the mapObject property

...
<l-freedraw ref="freeDrawRef"> ... </l-freedraw>
...

    ...
    this.$refs.freeDrawRef.mapObject.clear()
    ...

debounce

From my experience the rate events happened when drawing was a bit excessive, so I throttled the rythm of emitted event by default, setting this to :debounce="false" allow to bypass this settings (I don't remember why I coded it in the first place, there must have been a reason at one point). This might be removed later on if I find there's no use case for it.
