Fix incorrect status updates for lcn

[alengwenus]

Proposed change

Recent changes in the lcn integration broke functionality for several users due to incorrect handling of status messages from the hardware.
See #159104, #158892, #158059

To fix this, adjustments had to be made in the underlying library as well as to the parallel updates and their frequency.
Please note: Some of the LCN status changes are pushed to HA, while others need to be polled. For the former ones, the update interval has been set to 10 minutes, which is perfectly adequate.

The dependency upgrade is in a separate PR: #159277

Dear home-assistant team,

please release the fix as soon as possible, as it is very annoying to "loose" connections every few minutes/hours. Thank you so much!
