- CompositeDataQueueHandler will handle duplicate subscriptions sharing
the same config. Adding unit tests
* Refactor bug solution after review

but will just trigger a new subscription call when remapped.
- CompositeDHQ will handling symbol mapping and keep track of these
mapped configs to trigger unsubscribe accordengly. Adding unit tests
* Adjust solution after review
- To avoid breaking uniqueness of SubscriptionDataConfig will be adding
a private `mapped` property that will change equality of mapped
configs to avoid them clashing. Adding unit tests
* Rename IDQH subscription extension methods
