v1.2.0 - Taxi (shared mobility) update

Main changes

• Add taxi (aka. shared mobility) functions
  • A standard vehicle in UXsim just travel from A to B and disappear. This is like a private owned vehicle.
  • From this update, a Vehicle with mode="taxi" behave like a taxi. Specifically, they travel through a network by passing through specific nodes that are dynamically updated, simulating passenger pickup and drop-off.
  • New sub-module uxsim.TaxiHandler handles these matters.
  • Built-in vehicle-to-passneger matching methods are also available.
  • This addresses Issue #41
• From now on, we follow the Semantic Versioning rigorously.
