`with_header_from_request` for mock server

[alex-kattathra-johnson]

The ability to respond with a specific header based on request.

Not sure I understand what you mean - can you explain what you're missing? The library already provides a way to respond with a specific header (check the docs).

I want to respond with a Sec-WebSocket-Accept header based on the key that is sent in the request header.

Got it, so you need to set the response header to a dynamic value, like in Mock::with_body_from_request. I think this library could acommodate something like Mock::with_header_from_request with a similar signature. PRs are welcome ;)

@lipanski: Got you a PR! 😁
