Setup pokestops via JSON upload

[atis]

Also need to update core:

`/**

• GetFile

• @param $file_id
  */
  function get_file($file_id)
  {
  // Create response content array.
  $reply_content = [
  'method' => 'getFile',
  'file_id' => $file_id,
  ];

  // Encode data to json.
  $reply_json = json_encode($reply_content);

  // Set header to json.
  header('Content-Type: application/json');

  // Write to log.
  debug_log($reply_json, '>');

  // Send request to telegram api.
  return curl_json_request($reply_json);
  }
  `
