VIDEO-7378: Release TwilioVideo 4.6.1.

[ceaglest]

4.6.1 (October 15, 2021)

Bug Fixes

• Fixed an interoperability bug between JavaScript, iOS and Android SDKs which could cause subscription events not to fire in a Peer-to-Peer or Go Room. [VIDEO-7334] #211

Known Issues

• Audio playback fails when running a simulator on a Mac Mini. #182
• Carthage is not currently a supported distribution mechanism for Twilio Video. Carthage does not currently work with .xcframeworks as documented here. Once Carthage supports binary .xcframeworks, Carthage distribution will be re-added.
• Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. #34
• H.264 video might become corrupted after a network handoff. #147
• iOS devices do not support more than three H.264 encoders. Refer to #17 for suggested work arounds.
• Publishing H.264 video at greater than 1280x720 @ 30fps is not supported. If a failure occurs then no error is raised to the developer. [ISDK-1590]

Merging based upon CI, one approval and since the changes are routine and small in scope.
