multiple waypoints support

[novaknole]

Hi. Thanks for this nice package.

I am curious about 2 things.

1. is it possible to add waypoints all at once instead of adding them one by once?

a) if the answer above is no, then do I have to pay map load price for adding each waypoint one by one?

b) any other ways you can think of ? or I should use directions api directly to achieve 1 map load only and multiple waypoints?
