Always convert CRLF into LF-only line endings.

Browse source 
CRLF lineendings will happen on Windows,
but they shouldn't matter for Markdown content.

pulldown-cmark will parse them _nearly_ the same.
`<!-- toc -->\r\n` will actually be 2 HTML elements:
the `<!-- toc -->` part and a `\n` part,
whereas `<!-- toc -->\n` will be just one: `<!-- toc -->\n`.
That throws off our marker parser because we're looking for the latter only.

So by stripping our the CR (`\r`) we don't need to special-case anything.
The rendering will be the same.

Closes #35
