Update to use `res.status().send()`

[mkretschek]

express is deprecating the res.send(status, body). Should update this.

Maybe I could also allow a handler to be set that could override the middleware's behavior.

Hi @mkretschek ,

I created a PR for this #2.

Awesome! Thanks, man. I completely forgot about this. hahah

I just have to check what's wrong with the build. Will do that later today.
The change itself seems fine, though.
