Apply fun to each batch, sequentially or across future workers
Source: R/parallel.R
nsbi_batch_apply.RdThe parallel branch keeps at most one future per worker in flight and polls
for completions, so progress is reported as batches finish rather than in
one jump at the end. fun is called as fun(batch, tick): running
sequentially it ticks the bar itself, once per unit of work; running on a
worker it cannot report back mid-batch, so tick does nothing and the batch
is credited on completion.
