Add support for TLS ("SSL")

[CodeEagle]

Thanks for this great lib at first
Is this lib support SSL ?

Macro itself doesn't include NIO SSL for sizing reasons (and because SSL is not usually useful for Macro servers, as they usually live behind a frontend proxy like NGINX).

Having say that, we should create a MacroTLS eventually.

@helje5 thanks

I think we actually want to do this, create a MacroSSL/TLS package which integrates NIOTLS (similar to MacroLambda). Just not as part of this specific package.
