Socket "testing"

[StevenMiller123]

This homebrew uses a variety of socket-related behaviors to visually test how sockets are functioning.
The primary test code is a basic test of non-blocking socket communication, and I've baked in a couple socket-based logging backends to ensure multiple sockets can communicate simultaneously, and give a visual indicator of sockets functioning.

I've run these tests on a PS4 with no internet, and they run to completion without logging any errors.

I plan to continue increasing the scope of these tests over time, so I've marked this as a draft for now.
