Line Endings Cause Snapshot Mismatches

[mitsuhiko]

Description

Insta assumes that snapshots are LF terminated and confusing stuff happens (#170) if they are ending in CRLF.

Reproduction steps

1. create a test like this:

#[test]
fn test_crlf() {
    insta::assert_snapshot!("foo\r\nbar\r\nbaz");
}

2. cargo insta test --review
3. observe that the snapshot keeps being re-generated.
