Added wind_max_speed to sensor
New features:
- Added wind_max_speed to sensor.
Other code improvements:
- Clean field reading by mapping attributes to keys from AEMET
- Clean field reading by mapping fields to be transformed from m/s to km/h
- Round the decimals to 1 after transforming to km/h (like in AEMET API results), to avoid floating point precision issues
Thanks to @DjMoren for the whole work in this release.
