Add hydrocalm4 driver

[NightSkySK]

I would like to ask to add hydrocalm4 driver to the library

Here is example telegram which I've recorded on my device.

I've tried to add this meter using hydrocalm3 driver and it seams to work at least in scope which I added to my config. Cold and Warm Water meter also works fine.

packages:
  wmbus_gateway: github://IoTLabs-pl/wM-Bus-Gateway/packages/wmbus_gateway.yaml@v1.0.4

wmbus_radio:
  # This part of config is responsible for listening to any wM-Bus frames.
  # The same part of config is present in the factory firmware. 
  # Using links appear in the logs, you will be redirected to the wM-Bus Meters Analyzer
  # allowing you inspect the received frames, identify proper driver, 
  # check your decryption key and identify available fields in datagrams.
  # You may comment out this section if your meters are already configured
  # and you don't want to see the frames in the logs.
  on_frame:
    - then:
        - logger.log:
            level: WARN
            format: "Meter ID: %s"

Should I record any more sensors? Sorry I'm fresh to this topic.

We added a few new drivers including hydrocalm4. As we haven't yet tested all of them it is on a feature branch "wmbusmeters-1.20.0" for now. Would be great if you could check if the driver works properly with your meter and let us know.
