allow camel case of header name #377

I'm working on a customized websocket protocol which is using a header name "appKey" for authentication purpose. However, all customized header name is lower cased in this crate. Is there a public API which can enable acceptance of camel case of header name and don't auto lower case it?

I'm trying to use actix-ws, which is relying on this crate.

My understanding is that case sensitive HTTP header names is invalid usage. This might need to be handled outside of http.

According to HTTP standards your app must compare header names case-insensitively. Otherwise you will definitely run into compatibility problems. HTTP/2 header names are anyway lowercase.
