Enhancement: move

[danielb2]

objectPath.move(obj, 'old.path', 'new.path');

instead of:

 const path = objectPath.get(obj, 'old.path');
 objectPath.set(obj, 'new.path', path);
 objectPath.del(obj, 'old.path');

[danielb2]

ObjectPath.mv = function (obj, src, dst) {

    const data = ObjectPath.get(obj, src);
    if (!data) {
        return;
    }
    ObjectPath.set(obj, dst, data);
    ObjectPath.del(obj, src);
};
