GTFS: find direction head-sign from trips head-signs

[mmathieum]

As a developer, I want to automatically pick the right direction head-sign for trips

P1:

• [x] pick head-sign from multiple trip head-signs

P2:

• [x] link stops from same transit center (!= bay) #ets_bus
• [x] E/W/N/S direction converter #ttc_bus_streetcar #stm_buses
• [x] add missing direction ID to already splitted trips #sudbury
• [x] pick head-sign from non-descriptive trip head-sign (last stop name?)
  • [ ] combine [2] last stops to pick better direction?
• [ ] boolean option to append or replace with last stop name #airdrie
• [x] use stop_headsign from stop_times.txt ?
• [x] pick AM/PM from local arrival_time & departure_time in stop_times.txt ? #exo_crc #bc_comox

Later:

• [ ] ? force different trip head-sign for different trips
• [ ] ? automatic trip splitting
  • [x] try splitting based on trips not overlapping
  • [ ] try spitting based on 1 distinct trip (w/ != head-sign) included in loop trip (all stops) #us_juneau_route_1_3_4
  • [ ] split based on major transit hub stop ID (manually provided)
  • [ ] split based on stop where bus arrive and depart at distinct time (example also #exo_crc_14)
  • [ ] directions.txt from GTFS+ looks like we need when going back to (minified) GTFS instead of custom MT
