Emitters can define a `subchannel_key` which will be extracted (destructively) from each item and used to direct events to that subscription channel. Receivers can specific a `subchannel` to listen to. This combination allows a single emitter to fan out events to multiple separate receivers, e.g. for a webhook or incoming event stream that you want to split into more specific service handlers for each different event type.
