NetworkForge 1.2.0

Added

• networkforge traffic (Python: add_traffic, read_traffic_settings):
  time-of-day speeds for Valhalla. A settings file of time bands by road
  class ("primary roads at 60% on weekdays from 07:00 to 09:30") is put on
  a network as Valhalla's predicted traffic, and Valhalla's graph is
  written as a .tar file (the Network Analyst plugin's "From Tar").
  Only routes with a departure or arrival time use it; without a time
  every street keeps its normal speed. Needs the new traffic extra
  (pip install "networkforge[traffic]", pyvalhalla 3.9.0). See
  docs/traffic.md. networkforge info lists the settings' days, road
  classes and factor range under traffic.
• Single streets for traffic (--streets FILE, Python: street_bands):
  a line layer, one row per street and time band (days, time,
  factor, optional direction both/forward and osm_id / osmid).
  A line without a way id is matched onto the stretches it runs along,
  so it can be part of a long street or a new one. A street with rows of
  its own ignores the road-class bands. Lines that match nothing are
  named in a warning (--id-field) and in the done event's unmatched.
