x-webkit-deflate-frame

Apparently Safari still don't follow the standard regarding compression. Adding an alias för their variant will solve this issue

x-webkit-deflate-frame is a vendor prefix to deflate-frame which is not the same as permessage-deflate but very close. The only thing that differs is the negotiation of sliding windows.

By supporting this, the exact details of permessage-deflate parameters should be hidden better in a module and only expose the general idea to the rest of the code.

This is one example of how websockets/ws is overcomplicating things by exposing complicated parameters to the end user, while we take the path of having simple-to-use compressors. Things should be simple to understand for end-users and work everywhere.

It's not actually an alias, it has different negotiation rules. But yes Safari still use this and we have to support Safari
