Assert a command stdout string is equal to an expression.

Pseudocode:
(command ⇒ stdout ⇒ string) = (expr into string)

§Example

use assertables::*;
use std::process::Command;

let mut command = Command::new("bin/printf-stdout");
command.args(["%s", "hello"]);
let s = String::from("hello");
assert_command_stdout_eq_expr!(command, s);
