In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

##' QGIS Algorithm provided by SAGA Next Gen Import cru grids (sagang:importcrugrids). ---------------- Arguments ----------------  GRIDS: Grids 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer FILE: File 	Default value:	False 	Argument type:	file 	Acceptable values: 		- Path to a file SHIFT: Shift 	Default value:	true 	Argument type:	boolean 	Acceptable values: 		- 1 for true/yes 		- 0 for false/no 		- field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field 		- expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression

##' @title QGIS algorithm - Import cru grids
##'
##' @param GRIDS `rasterDestination` - Grids. Path for new raster layer.
##' @param FILE `file` - File. Path to a file.
##' @param SHIFT `boolean` - Shift. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
##' @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`.
