Noter frontend integration with map

[timwaters]

This PR adds in noter / annotations to the map where buildings with images in the noter are highlighted and images shown, and other buildings can be selected with prompt to edit them and add images and annotations

[timwaters]

The last commit adds support for assigning the outer relation of a building multipolygon as a "feature-state" attribute to the map polygon used for showing which buildings have annotations and for getting the id in the results panel. This will make it easier to open the editor around a multipolygon feature but is not perfect.

We can make it better with 2 changes, to the tegola config and the mbgl style file.

The first, to the tegola-config.toml file in the Antique repo, would add a building_id as an extra feature property in the query for buildings.

  sql = "SELECT osm_id, osm_id as building_id, start_date, ... planet_osm_polygon WHERE building IS NOT NULL AND way && !BBOX!"

And second to the mbgl-antique-style.json file in this repo, add a promoteId entry to the sources in the style file to change the id for the buildings layer.

  "sources":{
    "antique":{
...
      "promoteId":{"buildings":"building_id"}
    }
  },

mbgl-photomap.js should work with or without the suggested changes.
