This PR adds support for bus rapid transit (BRT) systems, mapped with the [approved tag](https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:highway%3Dbusway) `highway=busway`. BRT systems commonly appear in maps that also show light rail. Below are two examples of BRT in such maps.   Since BRT is equivalent in nature to light rail systems, this PR matches the zoom level of light rail, which is rendered at zoom 11+. BRT systems are relatively uncommon, so adding this support should have negligible impact on tile size. Below is a data rendering of [a BRT system](https://www.openstreetmap.org/relation/4051383#map=12/40.4068/-79.8646) in Pittsburgh, Pennsylvania.

layer:

id: "transportation"
|
|
description: |
|
|
**transportation** contains roads, railways, aerial ways, and shipping
|
|
lines.
|
|
This layer is directly derived from the OSM road hierarchy.
|
|
At lower zoom levels major highways from Natural Earth are used.
|
|
It contains all roads from motorways to primary, secondary and
|
|
tertiary roads to residential roads and
|
|
foot paths. Styling the roads is the most essential part of the map.
|
|
The `transportation` layer also contains polygons for features like plazas.
