Get ratings history of a FIDE player

Data points are encoded. Each number contains a year, a month, and an ELO rating.

2015081568 -> August 2015: 1568

Here's an example decoding implementation in JS:

  const decodePoint = point => {
    const elo = point % 10000;
    const dateNum = Math.floor(point / 10000);
    const year = Math.floor(dateNum / 100);
    const month = dateNum % 100;
    return [year, month, elo];
  };

Consecutive months with same ELO are omitted. For a given ELO, only the first and last month are provided.
