AudioPlayerView: Add sliders and gestures

This merge request adds:

• The brightness and volume sliders to the Audio Player's View to be able to adjust it without going to the control center.
• The status label support to display information about the playback status and updates (such as the seek duration for example).

This merge request also brings the addition of:

• A pan gesture to control the brightness and volume sliders of the Audio Player's view.
• A tap gesture recognizer to play/pause the audio playback by tapping the screen with two fingers.
• A pinch gesture in order to minimize the Audio Player without pressing the close button.
• A swipe gesture to perform the seek backwards/forwards when swiping left/right.
