Making the turn function more flexible (#4789)

* set and store highway and access classification for the turn function
* expose highway turn classification and access turn classification and speed to the lua profile turn function
* expose whether connection road at turn is incoming or outgoing
* add lua tests for exposed information to turn function
* update docs about attributes in process_turn
* add turn_classification info to docs
* adding warning if uturn and intersection dont match
* handle u turns that do not turn into intersection[0]
* split OSM link generation in an accessible coordinate function
