"fewest turns" refinement?

hey @anvaka,

nice lib!

how feasible is it to add some post-processing pass to produce a "fewest turns" route to reduce the number of left-right-left-right turns in the path at the expense of some configurable "cost" for additional distance added to the route.

i frequently find it ultra aggravating when a destination can be reached with 3 turns and an extra 0.25mi rather than 7 turns. it simplifies the directions and number of legs in each route. google maps has a habit of providing such "scenic" routes.

thanks!
