Please pass the sourceEvent to onMoveStart, onMove and onMoveEnd

d3-drag stops the even propagation at https://github.com/d3/d3-drag/blob/main/src/drag.js#L58 This makes client code cannot get on mousedown event. One possible fix is to pass the sourceEvent to onMoveStart, onMove and onMoveEnd, same as other handlers.

We updated the handlers for v10 and pass the source event:

export type OnMove = (event: MouseEvent | TouchEvent, viewport: Viewport) => void;
export type OnMoveStart = OnMove;
export type OnMoveEnd = OnMove;

Awesome. Thank you!
