Wrapper function to calculate terrain analysis statistics for a RasterStack

get_stats_df(
  fun,
  fun_name,
  ls,
  dem_file,
  lines = NULL,
  stat = c(median, mean, min, max, sd, e1071::skewness),
  stat_name = c("median", "mean", "min", "max", "sd", "skew")
)

`fun`	either `near_channel_stats` or `raster_stats`
`fun_name`	a character string specifying the name of the function in the column of the resulting `data.frame`
`ls`	a RasterStack of terrain analysis rasters
`dem_file`	character, DEM filename (used for fixing names)
`lines`	a SpatialLinesDataFrame
`stat`	functions, list of statistics to derive
`stat_name`	character, labels corresponding to `stat`
