Subject: Fix usage of `api_key` engine setting

The value of `params['api_key']` isn't read anywhere.
Writing directly into the header object solves this quite easily though.

> [Users can authenticate by including their API key either in a request URL by appending `?apikey=<API KEY>`, or by including the `X-API-Key: <API KEY>` header with the request.](https://wallhaven.cc/help/api)
