Get the language most used by an user

[iblancasa]

GitHub used to provide "the most used language" by an user in the user profile. When GitHub changed the UI, this information was removed.

The API provides with this information:

    {
      "login": "Koltharius",
      "id": 7522784,
      "avatar_url": "https://avatars0.githubusercontent.com/u/7522784?v=4",
      "gravatar_id": "",
      "url": "https://api.github.com/users/Koltharius",
      "html_url": "https://github.com/Koltharius",
      "followers_url": "https://api.github.com/users/Koltharius/followers",
      "following_url": "https://api.github.com/users/Koltharius/following{/other_user}",
      "gists_url": "https://api.github.com/users/Koltharius/gists{/gist_id}",
      "starred_url": "https://api.github.com/users/Koltharius/starred{/owner}{/repo}",
      "subscriptions_url": "https://api.github.com/users/Koltharius/subscriptions",
      "organizations_url": "https://api.github.com/users/Koltharius/orgs",
      "repos_url": "https://api.github.com/users/Koltharius/repos",
      "events_url": "https://api.github.com/users/Koltharius/events{/privacy}",
      "received_events_url": "https://api.github.com/users/Koltharius/received_events",
      "type": "User",
      "site_admin": false,
      "score": 1.0
    }

How can we get this information? The API allows to search user by location and programming language. For instance: https://api.github.com/search/users?q=location:Granada+language:python

One possible solution could be to query all the programming languages in the location.

This could be a problem: for the worst case, the number of queries to the API would be multiplied by 465 (the number of languages in GitHub).
