v2.1.x Chore - Implement logging when not using tty

[reactive-firewall]

Implement improved output via logging module

Introduce the python logging module such that when not invoked from a tty the module logs output such that client code just needs to adjust the logging fixtures to customize verbosity and logging redirection as they see fit.

alternatives considered

• logging only - less useful; removes interactive features already in-place. 🪚
• no output - bad for maintainability and not as useful; 🙅🏻

Additional context
also consider:

 try:
     data = data.decode('utf8') if isinstance(data, bytes) else str(data)
 except UnicodeDecodeError:  # pragma: no cover
+    if (_sys.stdout.isatty()):  # pragma: no cover
+        print(f"Debug: Received invalid UTF-8 data from {self.client_address[0]}")
     return  # silently ignore invalid UTF-8 data -- fail quickly.
