Voice and Banner instructions for OSRM

[ccritne]

Issue

I want to use OSRM API Call in Maplibre-Navigation adding voice and banner instructions. I was inspired by Valhalla keys and I added them to RouteStep.

The algorithm is based on these properties that can be set up into options to personalize the output.

key	description
verboseNavigation	Allows you to add voice and banner instructions
announcementsDistancesBelow500m	Determines how often to receive instructions under 500 meter.
announcementsWayMinimumDistance	Determines the distance from maneauver location to include way name into instruction.
distanceLastAnnouncement	Determines when to receive last announcement.
