SpscReceiver<T>.fromTransferable constructor
Reconstructs a remote-only receiver from a transferable representation.
Use with toTransferable to transfer a receiver across Web Workers
or Isolates. The reconstructed receiver always uses the remote path.
Implementation
factory SpscReceiver.fromTransferable(Map<String, Object?> data) =>
SpscReceiver._(-1, unpackPort(data['port']!),
metricsId: data['metricsId'] as String?);
