Audi A6 e-tron: Trigger battery preconditioning for ABRP charging stops

Please add support for sending the next ABRP charging stop to the Audi native navigation system as an HPC destination/waypoint, so the car can automatically trigger battery preconditioning.

Currently, A6 e-tron drivers have to manually enter the same charger again in the Audi MMI to enable preconditioning.

This would make ABRP much more practical as the primary navigation app.
