Idfm-api

- Fix Info Traffic API (update API to use the v2 endpoint)

Changelog:
- Fixed missing stops from export
- Added new method `get_line_reports` to fetch traffic information (replaces `get_infos`). This method uses a more complete API
- Replaced the pre-processed data files by a class fetching them at runtime

- Fix bug causing missing stops

- Fixed backward compatibility
- Added option to filter by line to `get_directions` method

- Removed lines with no stops
- Renamed `StopData.id` to `StopData.stop_id`, added exchange area information if available (exchange_area_id, exchange_area_name)
- stop_id and exchange_area_id are now identified by their full STIF identifier (ex: `STIF:StopPoint:Q:XXXXX:`, `STIF:StopArea:SP:XXXXX:`)
- Added option to filter by line when requesting traffic information for a stop (only works for exchange_area_id)
