feat(filter)!: new simpler filter API (#2092)

* chore: rename IReceiver subscribe

* feat!: new `subscribe() API that only takes in decoders and callback

* chore: `to_async_iterator` uses new function name

* chore: make `createSubscription` private, and shorten error handling

* chore: update subscribe return type

* tests: use new API

* fix: tests
