-Optional values to adjust output. There are certain cases where you need to set operands for proper rendering. However, this is occassionally. Results turn out well with the built-in defaults. You may launch AnsiLove with the option `-e` to get a list of basic examples, with and without operands. Note that columns is restricted to BIN files, it won't affect other file types. It's also worth mentioning that setting a certain operand requires to set all operands before, so if you need to modifiy the `icecolors` operand, you have to set `font` and `bits` as well. On the other hand, it's fine to set the `font` operand while not setting any of the following. Got that?
