##' @title QGIS algorithm - Colour normalized spectral sharpening

##' @param GRIDS `multilayer` - Original Channels. .
##' @param PAN `raster` - Panchromatic Channel. Path to a raster layer.
##' @param SHARPEN `rasterDestination` - Sharpened Channels. Path for new raster layer.
##' @param RESAMPLING `enum`  of `("(0) nearest neighbour", "(1) bilinear", "(2) cubic convolution")` - Resampling. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .complete_output logical specifying if complete out of `qgisprocess::qgis_run_algorithm()` should be used (`TRUE`) or first output (most likely the main) should read (`FALSE`). Default value is `TRUE`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
