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

##' QGIS Algorithm provided by SAGA Next Gen Export surfer grid (sagang:exportsurfergrid). ---------------- Arguments ----------------  GRID: Grid 	Argument type:	raster 	Acceptable values: 		- Path to a raster layer FILE: File 	Default value:	False 	Argument type:	file 	Acceptable values: 		- Path to a file FORMAT: Format 	Default value:	0 	Argument type:	enum 	Available values: 		- 0: (0) binary 		- 1: (1) ASCII 	Acceptable values: 		- Number of selected option, e.g. '1' 		- Comma separated list of options, e.g. '1,3' NODATA: Use Surfer's No-Data Value 	Default value:	false 	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 - Export surfer grid
##'
##' @param GRID `raster` - Grid. Path to a raster layer.
##' @param FILE `file` - File. Path to a file.
##' @param FORMAT `enum`  of `("(0) binary", "(1) ASCII")` - Format. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param NODATA `boolean` - Use Surfer's No-Data Value. 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`.
