Expose geometry

[jonathf]

Issue

There has been a request for accessing the geometry attribute:
VROOM-Project/pyvroom#95

The attribute is unaccessible on the vroom side, so this patch exposes it so it can be read from pyvroom.

Oops, sorry, I just realized pyvroom is already doing most things properly.. I don't know how I didn't see that last night, but there's already Input::set_geometry in pyvroom which is exactly what it needs. It's not on Solution but on Input class..

I think a few things will have to be amended (instead of exposing _geometry):

• the Input::set_geometry of the bindings is currently a no-op, it needs to take a boolean to set the _geometry
• the _routes_numpy conversion needs to add the geometry strings if present

Probably a bit more than that. I can look into it soon too. I'd update when working on it and let me know if you're first :)

Ah, okey, there are two "geometry" references.

Closes this PR to we have correct course of action in place.
