Shebang with Windows EOL

[PioMie]

We have a file with shebang header (because of Mac users).
We have core.autocrlf=true therefore the line endings on Macs are \n and Win \r\n.

When checking headers on Windows it never finds headers. It has to detect them in a file starting with:
#!/usr/bin/env node\r\n/**\r\n * Copyright\r\n */

There is a little mistake in hasHeader method:
var m = src.match(/(\r\n|\r|\n)/); does not fit to the:
src = src.slice(m.index + 1); - in case of Windows' EOL the are two characters instead of one.

I have a fix proposition in this pull request

Hi, @PioMie! I forked the project last year and added the following positive test-case which passes:

{
    code: "#!/usr/bin/env node\r\n/**\r\n * Copyright\r\n */\r\nconsole.log(1);",
    options: ["block", "*\r\n * Copyright\r\n "],
}

I believe you can get any version starting from 3.1.6 onward (maybe even 3.1.5).
