Deprecated furrr options

As of furrr 0.3.0, future_options() is defunct in favor of furrr_options().

future_options(globals = TRUE, packages = NULL, seed = FALSE, scheduling = 1)

`globals`	A logical, a character vector, a named list, or `NULL` for controlling how globals are handled. For details, see the `⁠Global variables⁠` section below.
`packages`	A character vector, or `NULL`. If supplied, this specifies packages that are guaranteed to be attached in the R environment where the future is evaluated.
`seed`	A logical, an integer of length `1` or `7`, a list of `length(.x)` with pre-generated random seeds, or `NULL`. For details, see the `⁠Reproducible random number generation (RNG)⁠` section below.
`scheduling`	A single integer, logical, or `Inf`. This argument controls the average number of futures ("chunks") per worker. If `0`, then a single future is used to process all elements of `.x`. If `1` or `TRUE`, then one future per worker is used. If `2`, then each worker will process two futures (provided there are enough elements in `.x`). If `Inf` or `FALSE`, then one future per element of `.x` is used. This argument is only used if `chunk_size` is `NULL`.
