Calculate descriptive statistics of raster as segmented by polygons

Source: R/tb_bluedjinn.R

calculate statitiscs of polygon based raster extraction. Returns a spatialpolygon dataframe containing decriptive statistics

poly_stat(
  rasternames = NULL,
  spdf = NULL,
  count = 1,
  min = 1,
  max = 1,
  sum = 1,
  range = 1,
  mean = 1,
  var = 1,
  stddev = 1,
  quantile = 10,
  parallel = 1,
  proj = "+proj=utm +zone=30 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs",
  path_run = tempdir(),
  giLinks = NULL
