Urban Noise add-on: /noise/point and the urban-noise layer

An Urban Noise add-on gates modelled road, rail, aircraft and commercial noise for six Canadian cities: GET /noise/point, an urban-noise catalog layer and overlays=urban-noise. Sold as a preview.

• GET /noise/point?lat=&lng= returns the modelled noise of the H3 hexagon (about 25 m) at a point in Calgary, Edmonton, Vancouver, Toronto, Montréal or Québec City: lden, lnight, a WHO-anchored score and label, the WHO 2018 exceedances and each source's level. A point outside them is 422 outside_coverage, with the covered cities.
• overlays=urban-noise colours any style by the score, and the tiles are at /layers/urban-noise/{z}/{x}/{y}, four H3 resolutions from zoom 0 to 18 in one source-layer, noise.
• The data is ODbL, derived from OpenStreetMap: every response carries meta.licence and the OpenStreetMap credit.
