Specify units for wind speed

For wind speed it would be great to have all the options from Open-Meteo's APIs available (unit code in parentheses):
- m/s (`ms`)
- km/h (`kmh`)
- mph (`mph`)
- Knots (`kn`)

The main reason is that in countries like Finland, wind speed is in m/s instead of km/h, so both are valid "Metric" units. Thanks!
