[Python Deprecation] `telnetlib` will be deprecated

[Acters]

telnetlib will be deprecated in newer python version. https://peps.python.org/pep-0594/#telnetlib

There is no real replacement at the moment. you will have to either make your own, find another library, or drop the python implementation all together as most are not really thinking of using it or even know it exists.
The bind to local port for insecure connect seems plenty useful for most, if not all, users.
