Adding a (friendly) name to a sensor

[DamianosS]

When creating these sensors

# 60 Hietzing towards Westbahnhof - first
- platform: wienerlinien
  firstnext: first
  stops:
    - '1630'

# 60 Hietzing towards Westbahnhof - next
- platform: wienerlinien
  firstnext: next
  stops:
    - '1630'

# 56A Hietzing towards BhF Atzgersdorf - first
- platform: wienerlinien
  firstnext: first
  stops:
    - '3752'

# 56A Hietzing towards BhF Atzgersdorf - next
- platform: wienerlinien
  firstnext: next
  stops:
    - '3752'

the created entities are

sensor.franz_asenbauer_gasse_first_departure
sensor.franz_asenbauer_gasse_first_departure_2
sensor.franz_asenbauer_gasse_next_departure
sensor.franz_asenbauer_gasse_next_departure_2

adding "name" or "friendly_name" to the sensor definition doesn't work.
