No attempts to reconnect after OSError

At first, I would like you to thank you for this amazing integration! Most of the time it works really well. However, I stumbled across this one issue.

Sometimes the JA-80T module disconnects -- the OSError and/or PermissionError exception is raised:

2024-05-05 22:19:56.061 ERROR (ThreadPoolExecutor-0_0) [custom_components.jablotron80] Unexpected error: %s
Traceback (most recent call last):
  File "/home/homeassistant/.homeassistant/custom_components/jablotron80/jablotron.py", line 842, in _read_data
    data = self._connection.read(64)
           ^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: [Errno 5] Input/output error

During handling of the above exception, another exception occurred:

However, after the module reconnects again, the integration does not attempt to resume connection, HA restart is needed. Also, as described in #97, the values remain stuck instead of reporting as unavailable. Overall, this is probably similar to the #165, maybe better exception handling is needed?
