Description
CmdStanPy has a nice progress bar that we can implement in R too.
We are currently using processx::run(..., echo=TRUE) so that the R user sees the output directly from CmdStan, but processx provides a lot more control than that and it looks like it has what we’d need behind the scenes for a progress bar even for chains in parallel.

Research direction
Start at the current processx::run(..., echo=TRUE) invocation and inspect the open pull request linked to this issue. Determine how progress output should work when CmdStan chains run in parallel; done means R users see a progress bar instead of only direct CmdStan output.
