Convert OSM tags into estimate of walk/wheel/cyclability

Some prior work: https://github.com/itsleeds/cyclability

The goal of this miniproject, part of #3, is to generate estimates of broadly defined cyclability. There are at least three definitions of how conducive to cycling different places and segments of roads and travel networks are:

• Level of Traffic Stress (LTS)
• Bikeability levels, which rates infrastructure based on the level of training needed to feel comfortable: Level 1 teaches basic bike-handling skills in a controlled traffic-free environment. Level 2 teaches trainees to cycle planned routes on minor roads, offering a real cycling experience. Level 3 ensures trainees are able to manage a variety of traffic conditions and is delivered on busier roads with advanced features and layouts
• CycleStreets’s Quietness rating from 1 (very unpleasant for cycling) to 100 (the quietest)

What should this be? A Python package, R package, Rust crate, set of scripts, report or other? To discuss! @dabreegster @Sparrow0hawk

My thinking: low level foundation to be used as building block could be handy and Rust seems good for that.
