Add option to grid_coordinates to return 1D coordinate arrays about verde

I agree with this! We would need to think what to do with the extra_coords. Any thoughts?

Good point! It doesn't make sense to use extra_coords and meshgrid=False together since the whole point of extra_coords is to get a meshgrid with constant values. So maybe we just return it as is (i.e. a single value)?

I agree that if we want to avoid allocating large coordinate arrays it doesn't make sense to generate huge extra_coords arrays with constant values. But it doesn't make any sense either to pass a single float (or list of floats) to extra_coords and get the same ones as output. What if we just avoid the trouble by ignoring extra_coords if we pass meshgrid=False?

Sounds OK to me. Probably doesn’t matter too much which way we go since using both options together is extremely unlikely (famous last words 🥲).
