Strip ANSI escapes from a &str, returning the printable content

This can be used to take output from a program that includes escape sequences and write it somewhere that does not easily support them, such as a log file.

For non-contiguous data, see StripStr.

Example

use std::io::Write as _;

let styled_text = "\x1b[32mfoo\x1b[m bar";
let plain_str = anstream::adapter::strip_str(&styled_text).to_string();
assert_eq!(plain_str, "foo bar");
