Suggestion to fix #42

[florisvdh]

As mcapply is not used directly anymore, it has been dropped (it errored anyway if parallel was not explicitly loaded).

The error for stopCluster was solved by importing it.

The parallel examples of download_zenodo were improved by attaching parallel.

New reprex with current state:

library(zen4R)
library(parallel)
download_zenodo("10.5281/zenodo.2547036", 
                parallel = TRUE,
                parallel_handler = mclapply,
                mc.cores = 2)
