* Use monotonically increasing channel_id
Using a monotonically increasing channel_id (instead of a Uuid)
reduces memory use under load by ~3%
* Use replace unbounded channels with bounded
This also slightly reduces memory use
* Heap allocate Event
Wrapping the Event struct in an Arc avoids excessive copying and significantly reduces memory use.
* Implement more efficient unsubscribe strategy
* Fix various Clippy lints; bump version
* Update config defaults
* Initial [WIP] implementation
This initial implementation works to send messages but does not yet
handle unsubscribing properly.
* Implement UnboundedSender
* Implement UnboundedChannels for concurrency
