refactor to pyvroom and pyvalhalla

[ejwillemse]

Change app from using OSRM and hygese to using:

• pyvalhalla (https://github.com/gis-ops/pyvalhalla)
• pyvroom (https://github.com/VROOM-Project/pyvroom)

See https://github.com/WasteLabs/streamlit_example_routing_app (notebooks) for some early experiments.

This should allow for complete local running, but it will increase computation time for extracting time and distance matrices.

• [ ] Replace OSRM cost matrix extraction with pyvalhalla.
• [ ] Replace OSRM-TSP and pyhgese solver with pyvroom
• [ ] Replace OSRM visualisation/summary with pyvalhalla
