esp32-s2: Adding authmode keyword

[BennyE]

While this works fine, I'm not entirely confident with my change around the following, as I need an additional variable.
e.g.

strcpy(authmode, "OPEN");

Can I get around this? I've tried/attempted to directly strcpy into cstr, but this resulted in an unhappy compiler.

I'm planning to add pairwise_cipher & group_cipher, unless you'd prefer to be a separate PR (thus this is a draft).

I suggested an alternative that I think will work.

Either way. Smaller is generally better.

One more minor nitpick. Thanks!
