In briskaR: Biological Risk Assessment

Add the raster value(s) of a Raster* object to element of sf object.

brk_exposureMatch(
  stackRaster_exposure,
  sf,
  stackTimeline,
  keyTime = "TIMELINE",
  key = "EXPOSURE"
)

`stackRaster_exposure`	The Raster* object
`sf`	the sf object
`stackTimeline`	sequence with matching to elements of RasterStack (length of stackTimeline must be the same as length of a list of stackRaster_exposure)
`keyTime`	name of the column to match exposure timeline from stackRaster_exposure
`key`	name of the new column
