Ability to Add Virtual BG in IOS

[seemantabiswas87]

Can you enable the support to add virtual bg in ios SDK.

Describe the solution you'd like

• Easier or convenient solution is to allow the startCapture and stopCapture to be able to override, so that we can send a customised track with custom videoCapturer. Seems like we are allowing this for the web/Android sdk but not in iOS.

Describe alternatives you've considered

• Livekit SDK can provide certain interface to enable the background blur effect or adding image in the BG
• Any other solution is also very welcome.
  Additional context
  Please let us know if you already support it or if we can achive it in some way.

This is a must have item for a lot of people. Customers won't use video conferencing apps that don't support this.

We also are interested in this so we can also insert our own track processor, essentially to do other things to the video (for example, have a gesture recognizer and then modify the video based on those gestures).
