Support for the KHR_audio extension

[ikonnow]

Is your feature request related to a problem? Please describe.
I would like to test the KHR_audio extension with blender, but there is no integration for this extension yet. This is a problem because i need .glb files containing the full scene context for game engines / web.

Describe the solution you'd like
I would love to work with the KHR_audio extension as soon as possible.
This would allow me (and everybody else using this addon) to use blender as a tool for creating immersive audio-visual experiences. I understand that the KHR_audio extension is still in testing phase, but it should be available to test on a testing branch.

Describe alternatives you've considered
The only alternative I have found is Gestaltor, which is a subscription-based software that supports the KHR_audio extension. However, I prefer to use blender because it is free and open source.

Additional context
The KHR_audio extension is a new standard for adding spatial audio to glTF models, which are widely used for 3D graphics on the web. It would be great if blender could support this extension, as it would make it easier for developers and artists to create and share 3D content with sound.
