Update Python CLI Guide

The following meshtastic command arguments don't work reliably. They either need to be fixed or the documentation updated:

--test This argument throws the following error message: "Test module could not be important. Ensure you have the 'dotmap' module installed."

--reply This argument results in a connection to the radio, then no further apparent action. Eventually, it fails with the following error message:
Exception in thread Thread-2:
Traceback (most recent call last):
File "/home/rhadow/miniconda3/lib/python3.12/threading.py", line 1073, in _bootstrap_inner
self.run()

--set-owner-short This argument does not reliably reset the last four characters of the MAC address to uppercase. At least, it doesn't always stick.

--dest user.id (i.e. --dest '!b03bb4f8') works fine; num (i.e. --dest 2956702968) doesn't. The best you can hope for is "Received an implicit ACK. Packet will likely arrive, but cannot be guaranteed." What is an implicit ACK?
