fix(data-tracks): handle PushFrameErrorReason associated values

The 0.31.2 bindings give PushFrameErrorReason cases an associated `message: String` and
conform it to Swift.Error, so `catch PushFrameErrorReason.QueueFull` no longer matches.
Catch the error and pattern-match the case, rethrowing other variants.
