Planning shade routes

[Pakillo]

We need to find the best route between two points (ideally, two addresses or geoplaces as in Google Maps or Openstreetmap) with the conditions that

• route must follow streets (ideally from OSM), i.e. not being a direct line between the two points. Must be possible to make it walking

• route must minimize cost, in terms of selecting the most shaded routes as coming from the shade raster for that date and time
