2.0.2 Futureverse

[markusul]

• All functions that support parallel processing now use futures. And all usages of futures are updated. If mc.cores is greater than 1, we use multicore if possible and multisession otherwise Closes SUGGESTIONS: Simplify parallelization code by using future::multicore instead of mclapply() #13 while we undo changes to future::plan() afterwards Closes Please undo changes to future::plan() #12 . If mc.cores is equal to 1, a predefined custom future::plan() is used. (Or sequentially processed if no plan was defined.)
• We improved the RAM usage of many potentially parallel calculated processes.
• For all progress updates, we now use progressr
