STDIN support in CLI interface

[DurandA]

I think it would be a nice addition to support standard input in CLI as an easy way to automate PDF generation with shell scripts. Would it be easy to implement?

Should be, the markdown-pdf module is a through stream so you should be able to pipe in and out:

process.stdin.pipe(markdownpdf()).pipe(process.stdout)

I'd definitely accept a pull request to the CLI that implements this!

echo "# Some markdown\nYay" | markdown-pdf

Zshell workaround:

markdown-pdf -o output.pdf <(echo "# Some markdown\nYay")

It's not stdin, but it does stream and doesn't hit disk.
