Add TLS socket protocol adapter

[cstrotm]

A generic TLS socket connection via the N: device handler would be useful to access Gemini server

I'm working on an Gemini server for the ABBUC webpage contents and would like to create a Atari 8bit Gemini Browser

ESP-IDF does indeed have an API for accessing TLS wrapped sockets:

And I did attempt to start on this in May 2021, but got stuck.

Does anyone want to take a whack at this?
