Audio: Override copy and clone methods to include missing properties

[Byongho96]

This PR addresses issues with the Audio class's clone and copy methods.

Description

The Object3D's clone method, inherited by Audio, creates a new instance without passing additional parameters. This causes errors when cloning an Audio object, as the listener is mandatory for its creation.

Proposed Solution
The clone method has been overridden to align with the expected behavior: reusing the existing listener when creating a new Audio instance.

The copy method has been overridden to correctly handle properties specific to the Audio class, ensuring all relevant data is properly transferred.

Exception Handling for sourceType

• 'buffer':
  The play method regenerates the source internally using context.createBufferSource.
• 'audioNode', 'mediaNode', or 'mediaStreamNode':
  These source types are single-use and cannot be reused across multiple connections. A warning is logged, and these sources are excluded from the copy process to prevent misuse.

I have always hesitated with adding clone() and copy() to audio classes since you are never able to copy the exact same state of the audio to another object.

Granted, the derived methods from Object3D are not useful right now so it seems the proposed versions of the PR are an improvement.
