Enable Transport Line ID’s in response

[BK01]

Current State:
The BC Route Planner response does not include a list of Transport Line ID’s (TLIDs).

Test cases: All routes (Truck and Non-truck) with &enable=tl. This should be disabled by default.
https://router.api.gov.bc.ca/directions.json?points=-123.70794%2C48.77869%2C-123.53785%2C48.38200&enable=tl
https://router.api.gov.bc.ca/truck/directions.json?points=-123.70794%2C48.77869%2C-123.53785%2C48.38200&enable=tl

Future state:

• Include a list of the TLIDs associated with a route if the request includes an enabling parameter value (not included by default).
• Include TLIDs in the response for both truck and non-truck requests (if specified in the request)
• The list of TLIDs do not need to be linked to directions.
• TLIDs returned in order from start to end

Out of scope:

• Additional work to unpack TLIDs within joined Ferry routes.
