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

https://github.com/mpio-be/rangeMapper/blob/575046b8b390dd024911bc8cf912e8b83580da51/R/4_maps.R#L249-L257

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.
