otii_is_logged_in command appears to fail from Linux on Python 3.10

[pscheidler]

When trying to connect from a Raspi running Ubuntu 22.04, Python 3.10 using

        client = otii_client.OtiiClient()
        self.otii = client.connect()

I get

File "/home/ubuntu/.local/lib/python3.10/site-packages/otii_tcp_client/otii_client.py", line 170, in connect
    self.otii = Connect(host, port, try_for_seconds, licensing, credentials, licenses)
  File "/home/ubuntu/.local/lib/python3.10/site-packages/otii_tcp_client/otii_client.py", line 59, in __init__
    if not self.is_logged_in():
  File "/home/ubuntu/.local/lib/python3.10/site-packages/otii_tcp_client/otii.py", line 169, in is_logged_in
    raise otii_exception.Otii_Exception(response)
otii_tcp_client.otii_exception.Otii_Exception: {'type': 'error', 'errorcode': 'Invalid command', 'cmd': 'otii_is_logged_in', 'trans_id': '1', 'data': {}}

I can work around this by using

        client = otii_client.OtiiClient()
        self.otii = client.connect(licensing='manual')
        print(f"Using credentials {credentials=}")
        self.otii._login(credentials)
        try:
            self.otii.return_license(LICENSE_ID)
        except Exception as e:
            print(f'Ran into error, hopefully license is available. Error = {e}')
        assert self.otii.get_licenses()[0]['available'], 'License not available'
        self.otii.reserve_license(LICENSE_ID)

Our system does have the otii server already running, and we should already have a license. Please let me know if you need more info
