Body: <p>Chess.com reports that 17-year-old <a href="https://www.chess.com/news/view/frederik-svane-2-gm-norms-in-24-hours" rel="nofollow noreferrer">Frederik Svane has scored 2 GM Norms In 24 Hours</a> and asks if this is a record:</p>
  <blockquote>
  <p>17-year-old Svane, the youngest of the two brothers (Rasmus recently turned 25), scored his first GM norm in October 2021 at a round-robin in Kiel, Germany, where he finished in second place and reached the necessary 6.5 points by winning the last two rounds on demand.</p>
  <p>The second GM norm came last Friday, when Svane finished another closed GM tournament, this time at the local Hamburg Chess Club. The scenario was almost the same: he again came second with the necessary 6.5 points, this time winning the last three rounds on demand.</p>
  <p>Meanwhile, Frederik had played a pretty good Bundesliga season for his Hamburg club, where he had collected six points in the first eight rounds. You may guess it: also here, against pretty strong opposition, he needed 6.5 points for a GM norm. His opponent on Saturday, GM Eduardas Rozentalis, who had celebrated his 59th birthday the day before, didn't mind a quick draw, and so Svane had achieved something unique: two norms in a day! [Ed: Friday and Saturday are not the same day. Stick to 24 hours]</p>

  Well, this was painful. The data inserted by FIDE was inconsistent, there were duplicate entries and some records didn't even exist. Anyways:
  
  ### No, this does not seem to be a new record!
  
  **[Peng, Li Min](https://ratings.fide.com/profile/14112620)** ([title application](https://ratings.fide.com/crt/main227056.pdf)) won two GM norms **in the same day** (*Elitzur GM Winter 2020 A Stage 1* and *Elitzur GM Winter 2020 C Stage 1* both ended on 2021-03-11)

  I needed to check 2 large [categories of players](https://ratings.fide.com/titles_page.phtml):
  
  1. Those who had earnt at least two GM norms (Norms tab).
  2. Those who already had the GM title (Applications tab).

  1. The JSON data is available in [this URL](https://ratings.fide.com/a_titles.php?country=latest&title=%22GM%22). We're only interested in the player's name and their id. Now, for each of the players, make a request to `https://ratings.fide.com/a_titles.php?record2=` to get information about the norms they've earnt.
  2. For those who already are GMs this is slightly harder. For each FIDE Council/PB, fetch all application by making a GET request to `https://ratings.fide.com/a_titles.php?pb=` (`1 < id < 70` at the time of writing), get *only* the Grandmaster applications, for each applicant make a request to `https://ratings.fide.com/a_titles.php?record=`. Parse the HTML and sort as above.
  
  Combine both steps, sort and output.
