Support for GIll Windsonic Anemonemeter

**Describe the problem you have/What new integration you would like**

I would like to get the Gill Windsonic to work with the ESP32 platform, as this will make it hugely simplified to deploy. And use the Home Assistant for managing data and display them.

**Please describe your use case for this integration and alternatives you've tried:**

I have tried to make itt work as a custom sensor, but not quite got it working, but I will include what I have done so far, maybe that can be used to make an sensor for the windsonic. I can learn more about this in the process

This Windsonic sensor communicates via the RS232 interface, via an rs232 to TTL adapter to an UART port on the ESP32.

It's sends NMEA 0183 sentences with fixed field length each second, I ahve decoded this in my windsonic.h file that I include here.

I have come so far that the ESP reads and publish the data to the log on the usb interface, or OTA interface.
Futher I haven't manage to come in the publish to lovelace process. I'm a bit stuck on this point.

It would also be nice to learn what's needed to make this it's own sensor integrasjon in ESPHome platform
