interpret ansi codes

In fzf, if I want specific items to be in different colors, I can do this:

```sh
echo -e "\033[33mYellow Item 1\033[0m
\033[33mYellow Item 2\033[0m
\033[33mYellow Item 3\033[0m
\033[35mPurple Item 4\033[0m
\033[35mPurple Item 5\033[0m" | fzf --ansi
```

but I can't find a way to achieve this with the library.
