Allow removal of trackers and clearing of progress

[apprehensions]

Is your feature request related to a problem? Please describe.
Progress bars remain, even after completing. The same can be said for Progress when all Trackers has been satisfied.

Describe the solution you'd like
func (p *Progress) Clear() to clear all trackers.
func (t *Tracker) Remove() to remove the tracker from Progress

Hey @apprehensions can you share code or video of what you mean by the progress bars remains after completion?

I'm thus video you made, after the trackers finish with done!, they remain there. I would like for them to be removed from the terminal instead.

Hey @apprehensions ... I know this is 5 months late, but I've implemented a "RemoveOnCompletion" option on the trackers. Check it out. It is on the main branch. If it works for you I can cut a new tag for you.
