[feature request] typing for change event

[MathieuDerelle]

as described here https://github.com/SortableJS/Vue.Draggable#events

all other events seems to be from Sortable and have typings
https://github.com/DefinitelyTyped/DefinitelyTyped/blob/55e8d53164cd8ee5411a3e5769a1fe4d855bea51/types/sortablejs/index.d.ts#L113

however the change event does not come from Sortable and I havent found its type in
https://github.com/SortableJS/Vue.Draggable/blob/master/src/vuedraggable.d.ts

I'd rather use a typing instead of resorting to any

PS: as recommended, I tried to get an answer on stackoverflow, but didn't get any
