ConvertSD not allowing T < 0 °C

convertSD gives temperatures that are always >= 0 °C, with several values exactly equal to 0 °C.

See below an example with some personal data, I'll try to reproduce that with data from seineBasin2. It seems the argument temperature = TRUE is not passed to other functions. See in https://gitlab.irstea.fr/in-wop/airGRiwrm/-/blob/dev/R/ConvertMeteoSD.R, output <- lapply(id_runoff, ConvertMeteoSD, griwrm = x, meteo = meteo) or

  output <- ConvertMeteoSD(
    meteo[, upperIDs, drop = FALSE],
    areas = areas
  )

> griwrm
