      A list of valid current currencies according to ISO 4217.

      The list was obtained from https://www.six-group.com/en/products-services/financial-information/data-standards.html#scrollTo=isin

          The decimal positions that lead to this currency smallest unit.

          For example: since Japanese Yen (JPY) have no cents, this value is 0.

          On the other hand, since the US Dollar (USD) is composed of cents, and each dollar equals 100 cent, this value is 2.

          To convert from normal unit (Dollar) to smallest unit (Cent), multiply by `10^decimal_positions`.
          To convert from smallest unit (Cent) to normal unit (Dollar), divide by `10^decimal_positions`.

      A bunch of rates between currencies, taken from our invoicing cycle in February 2024. 

      These are hardcoded and so will become outdated, but it's the best we have now since we don't have a live feed for exchange rates.

          The rate between the two currencies. You should read it as the amount of target currency you get for each unit of base currency.

          For example: for the combination EUR-GBP, a rate of 0.8 means you get 0.8 GBP for 1 EUR.

          Rates between same-currency pairs are always one.
