Description of what changed

Add new $PSStyle.Progress.UseOSCIndicator setting to use conemu's OSC indicator to show progress in the terminal window, which is also supported by Windows Terminal. Since this is a custom OSC that isn't widely supported, it defaults to $false. Since this is an advanced setting not supported by many terminals, had to give it a technical name. iTerm2, for example, uses ESC]9; as a notification OSC sequence so you get a pop-up dialog instead of progress.
