It'd be nice to have a method or hook where one could define clean-up actions on a RemoteProgress indicator. The update() method allows one to update progress info, but there's no way to know when a RemoteProgress indicator completes. I'm envisioning a complete() method on a RemoteProgress instance that would be implemented by childclasses that GitPython would call once an action that takes a progress indicator completes.

Think for example a progress indicator that after the operation has completed spits out a "progress complete" message. Right now I do that by passing the RemoteProgress instance to clone_from and then after the clone_from call comes back I do a separate update to indicate operation complete. This is fine for basic sequential (ie multiple line) output to stdout, but say if you want to use a library that does progress bars (ex: Enlighten or alive-progress) that updates the same line in the terminal window, suddenly it gets a bit awkward as "ownership" of that line on screen is shared between the caller of clone_from and the RemoteProgress instance.
