Like Rust's built-in `assert_eq` macro, but for token streams. Passes them through rustfmt, and shows a pretty diff.

# assert_tokens_eq

Like Rust's built-in `assert_eq` macro, but for token streams.
Passes them through rustfmt,
and shows a pretty diff
(powered by [pretty_assertions]).

## How it works

You write:

```rust
let got = something_that_generates_rust_code();
let expected = quote! {
    #[no_mangle]
    extern "C" fn foo(
        input: *const ::libc::c_char,
        input_len: ::libc::size_t,
        input3: *const ::libc::c_int,
        input3_len: ::libc::size_t,
    ) {
        fn foo(input: Arc<str>, input2: Arc<str>) {}
        unimplemented!()
    }
};
assert_tokens_eq!(got, expected);
```

and you get:
