Split HGV vehicle types into separate profiles

[aoles]

In order to resolve vehicle-type access restrictions already at graph building stage current hgv subprofiles specified through vehicle_type will be split into 3 separate driving profiles:

• :truck: Hgv
  • [ ] delivery
• :tractor: Agricultural / Forestry
• :bus: Bus

vehicle_type=goods are defined by the OSM tag:

Access permission for goods which are not heavy goods vehicles; in most countries, goods vehicles whose maximum allowed weight is below 3.5 tonnes.

These will be integrated into driving-car profile which will be extended by options to specify

• [ ] goods
• [ ] delivery
