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

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.
