Import method that does not exist anymore

It seems that there is a leftover import of a previously deprecated method/module draw_dispatch_cr here:

Hi Alessio,

thank you for spotting this. This module has been removed in the last release of commonroad-io. We will also remove it from the drivability checker.

Best,
Gerald

For those coming from jupyternotebook tutorial, just comment out the import line

from commonroad_dc.collision.visualization.draw_dispatch import draw_object

The plan is to no longer support draw_dispatch_cr.
