Feature request - Support for custom authorizers

[okachobi]

AWS supports custom authentication/authorization through custom authorizers. This involves the client sending in an optional authorizer name, an auth token, and digest for the token based on a cert. These must be sent in the Websocket headers. Apparently web browsers won't permit this (?) but CLI nodejs environment will.

This mqtt library is very simple and straightforward in syntax. If it supported custom authorizers it would do everything I need.

Is there any docs on this I can read?

They're somewhat poorly documented, but this covers the format of the request...
