 The file contains the individual states resolved with the directions and delays of the state. The size of the file is always a multiple of the RSI's `size`. Sprites are ordered from the top left to the bottom right, always going horizontally first. The amount of sprites per row or column is always made to be as equal as possible, favoring rows to be longer than columns if the amount of states is not able to be divided perfectly.
