Allow up to 9 navigation via points when BRouter is selected
BRouter has become a fantastic component of the offline navigation system. BRouter itself supports up to 9 via points. I used to use BRouter directly but recent Locus integration has meant the Locus "Navigate to" function is generally faster and more convenient. However Locus limits the number of via points to 3. Why not support up to 9 when BRouter is selected as the compute source? Believe it or not there are plenty of times when I try to "steer"/ encourage along a different route, and is only possible with more vias.
