Function colorize_string 

pub fn colorize_string<S>(input: S) -> String
where
    S: Into<String>,

Finds all keys in the given input. Keys meaning whatever the logger uses. Something that looks like <key>. And replaces all those keys with their color, style or icon equivalent.

This is a wrapper around the format_string function, it always passes true for the second parameter. If you want to have the ability to both colorize and plain remove the tags out of the strings, you should that function instead.

This function does not take into account custom styles, you need the struct for that
