Ansi option being ignored on the library

[mpasa]

It seems the ansi option using Skim as a library is being ignored.

How to reproduce

Create a new cargo project

cargo new skim_ansi

Add skim and ansi_term as libraries. The last one will be used to produce a colored string.

Cargo.toml

[package]
name = "skim_ansi"
version = "0.1.0"
edition = "2018"

[dependencies]
skim = "0.8.1"
ansi_term = "0.12"

Run skim as stated in the documentation, with a colored string generated by ansi_term.

src/main.rs

use skim::prelude::*;
use std::io::Cursor;
use ansi_term::Colour::Red;

fn main() {
    // Skim options, ansi is being activated
    let options = SkimOptionsBuilder::default()
        .height(Some("90%"))
        .ansi(true)
        .build()
        .unwrap();

    // Input line. We use ansi_term to produce a red string
    let input = Red.paint("A red string").to_string();

    let item_reader = SkimItemReader::default();
    let items = item_reader.of_bufread(Cursor::new(input));

    let selected_items = Skim::run_with(&options, Some(items))
        .map(|out| out.selected_items)
        .unwrap_or_else(|| Vec::new());

    for item in selected_items.iter() {
        print!("{}{}", item.output(), "\n");
    }
}

Expected behaviour

• The string should be colored while in the skim window
• The result should also be colored

Actual behaviour

• The string is not colored in the skim window. It appears as ?[31mA red string?[0m.
• The result is colored correctly.

[lotabout]

Same issue as #300 , should be addressed in master branch.

ansi option now belongs to SkimItemReader and is removed from SkimOptions.
