- `dbW_weatherData_round()` now rounds both "weatherList" and "weather data frame" objects; argument "digits" can now also be logical (if TRUE, then digits takes the default value of 4) or not finite (e.g., NA; not finite values return the input without rounding).
- argument "round" of `dbW_dataframe_to_weatherData()` is deprecated and changed the default value from rounding to 2 digits to no rounding (NA) - recommended replacement is a separate call to `dbW_weatherData_round()`.
- argument "digits" of `dbW_generateWeather()` changed the default value from rounding to 4 digits to no rounding (NA)

- `dbW_generateWeather()` gained `"return_weatherDF"` and now returns a user requested weather object type.
If `return_weatherDF` is `TRUE`, then the result is converted to a data frame where columns represent weather variables; otherwise, a list of elements of class `swWeatherData` is returned (as previously).

- `dbW_imputeWeather()` combines the use of the weather generator and `rSW2utils::impute_df()` for replacing missing weather values

- `dbW_imputeWeather()` simplifies the weather section of the demo vignette substantially

`dbW_substituteWeather()` replaces missing weather values in one weather data object with values from a second weather data object

…of approaches

Approaches are linear interpolation for short missing spells, possibly fixed values for short missing precipitation spells, substitution from a second weather data object, and finally replacement with long term daily mean values

New family of functions `sw_meteo_obtain` that obtain (download) weather data from external sources and prepare for use by `"rSOILWAT2"`
* `sw_meteo_obtain_DayMet()` obtains and formats data from `"Daymet"`
* `sw_meteo_obtain_SCAN()` obtains and formats data from `"SCAN"`

- vignette "demo" is simplified thanks to `sw_meteo_obtain_DayMet()`
