#patch-for-review:
[x] https://gerrit.wikimedia.org/r/824162 repeats what was already done in https://gerrit.wikimedia.org/r/763245, but in the wrong codebase.
[x] https://gerrit.wikimedia.org/r/824410
[x] https://gerrit.wikimedia.org/r/824698
[x] Actually tag the release. It appears this is done [exclusively on npm](https://www.npmjs.com/package/@wikimedia/mapdata), not via a git tag, branch or anything.
[] https://gerrit.wikimedia.org/r/825718 use it in Kartotherian
[] https://gerrit.wikimedia.org/r/c/826224 use it in Kartographer
For future reference:
* Update the version number in package.json. Check if package-lock.json needs an update as well (run `npm install`). Make sure all this is merged to master.
* `git tag v0.7.0`. This is sometimes done without the `v`, but it seems it's convention to have it.
* `git push --tags`
* `npm adduser` if this was not done before.
* `npm publish`
