Add new wind parser: RFLINK R51

[Minims]

Add wind as windspeed value. Seems new on RFLINK R51:

2024-02-05 13:37:21.286 DEBUG (MainThread) [rflink.protocol] received data: 20;70;TFA;ID=0ade0d;WIND=0011;

According with the RFLink "List of Data Fields: (LABEL=data)" this seems a RFLink bug:

• https://www.rflink.nl/protref.php

The RFLink allowed labels (related to wind) should be:

WINSP=9999 => Wind speed in km. p/h (hexadecimal) needs division by 10
AWINSP=9999 => Average Wind speed in km. p/h (hexadecimal) needs division by 10
WINGS=9999 => Wind Gust in km. p/h (hexadecimal)
WINDIR=123 => Wind direction (integer value from 0-15) reflecting 0-360 degrees in 22.5 degree steps
WINCHL => wind chill (hexadecimal, see TEMP)
WINTMP=1234 => Wind meter temperature reading (hexadecimal, see TEMP)

IMHO that should be addressed in the RFLink side (now that it seems active again).

The documentation does not always align with what you encounter in practice with RFLink is my experience. I removed Python 2.7 support in the master branch so the CI check should pass. After it passed I'll merge the PR.

I have also ask the RFLINK team to check if it'a bug or not.
