v2.0.0a Minor Bugfixes

This is a small service release with internal changes only.

While the plugin worked fine in a Python 3.10 / pymodbus 3 / Modbus RTU or TCP / Trovis 5579 environment,
a combination of Python 2.7 / pymodbus 2 / Modbus RTU on a Trovis 5576 threw some weird log entries.

Fixed in this release.

Release v2.0.0

2.0 changes:

Added support for Python 3.8+ and pyModbus3 (auto-switch between pymodbus2.2+/3.0+)
Added ModbusTCP support (for adapters with built-in TCP/RTU gateway like USR-TCP-K7 or USR-TCP232-E2)
Changed connection behaviour - added connect() and disconnect() to regular polls (formerly only at startup)
Updated register/coil tables, added new information, revised existing information, included Rk3 for 5579
Updated plugin.yaml: Rev 2 in format x.x.x, status 'ready', added 'werte' attribute to prevent errors in log
Removed unnecessary development files (templates, tools, assets) from official shNG-Plugins repo
Updated trovis.yaml items file, added Rk3+Sensors (e.g. for 5579)
New optional item attribute 'invalid_to_zero' to change response of 32767 (=switched off/unavailable/error) to 0

Release 1.0

This release includes the latest bugfixes, changes and amendments.
It replaces older files in /plugins/trovis_557x.
Please do not forget to delete pycache if manually installed.

Initial release

As the plugin is running well and smooth meanwhile, it is time to get it to the first release.

Still only reading out of registers/coils (no writing intended so far), and still without smartHomeNG Web Interface support.
