Full Currency List on Minor Units Format

We expanded the Minor Units Format reference page with complete lists of the currencies that do not use 2 decimal places. It now names every currency with no minor unit (0 decimal places) and every currency with 3 decimal places. We also clarified that the number of decimal places follows the ISO 4217 scale, not the smallest physical coin or note (for example, TWD uses 2 decimal places).
