Add Progress Bar for Playback

[qStivi]

I would like to request the addition of a progress bar to the Discord music bot interface. The progress bar should display the current position within the track and update in real-time as the track plays.

Rationale:

A progress bar will provide users with a visual representation of the track's progress, making it easier to understand how much time has elapsed and how much is remaining. This will enhance the overall user experience by providing more information at a glance.

Features:

• Display current position within the track.
• Update in real-time as the track plays.
• Show total track duration.

For the progress bar feature, I propose using dedicated instances that keep track of the current playback position and update the corresponding Discord chat message in real-time. These instances should be responsible for accurately tracking the progress and ensuring that the progress bar reflects the current state of the track. Implementing this with dedicated instances will help maintain consistency and reliability, providing users with an accurate visual representation of the track's progress.
