Using set_max_refresh_rate prevents bar from updating, is not defeated by tick/flush

[ZoomRmc]

In my case, I'd like to set the bar to the exact final total number in case the process doesn't go to completion.
No combination of set/tick/flush does get me an updated state when the ProgressBar goes out of scope.

Looks like there's no final redraw upon exiting the thread. At first I though it might be some kind of a race condition, so checked with sleeping the main thread to no avail.

Some possible solutions in order of preference:

• Make flush or tick ignore the refresh rate.
• Expose a manual redraw.
• Add a finish_with(final: u64) - not ideal, as the ProgressBar.count is not public (why?), which means a duplicating variable is necessary on user's side.
