Avoid passing `...` as a global variable to `future_lapply()`

[HenrikBengtsson]

You're using something like:

f <- function(X, ...) {
  future_lapply(X, FUN = function(x) g(x, ...))
}

where ... is passed to g() as global variables, in

rangeMapper/R/4_maps.R

Lines 249 to 257 in 575046b

	o = future_lapply( unique(cr$cell_id),
	function(i){
	x = cr[cell_id == i]
	E = try(fun(x, ...), silent = TRUE)
	E = data.table(E)
	E[, cell_id := i]
	E
	}, future.seed = TRUE )

It's better to pass ... as arguments as in:

f <- function(X, ...) {
  future_lapply(X, FUN = function(x, ...) g(x, ...), ...)
}

I've created PR #9, which fixes this.

Your current approach will give an error in the next release of the future package.
