This PR uses a Map instead of an Object for BaseChannel.consumers. It should improve the performance while running in node, as the amount of V8-HiddenClasses will be reduced.
Use Case: If in your implementation alot of consumers get created and canceled, alot of unique V8-HiddenClasses will be created in V8 at runtime.
Information regarding HiddenClasses:
