language option seems not to be working

[Ana Laura Diedrichs]

It seems that the language parameter is not used by the library.

`

tmp <- get_current_forecast(37.8267, -122.423, units="si", language ="de")
tmp$daily$summary
[1] "Light rain in the morning."
[2] "Partly cloudy throughout the day."
[3] "Breezy in the afternoon and rain starting in the afternoon, continuing until evening."
[4] "Partly cloudy throughout the day."
[5] "Mostly cloudy throughout the day."
[6] "Mostly cloudy throughout the day."
[7] "Mostly cloudy in the morning."
[8] "Overcast throughout the day."
