### Feature Request: Add Support for `stop` Method in Kafka Consumer

### Feature Request: Add Support for `stop` Method in Kafka Consumer

#### Description
The `stop` method is currently not supported in the Confluent Kafka JavaScript client, as noted in the [migration guide](https://docs.confluent.io/kafka-clients/javascript/current/migration.html). The recommended workaround is to disconnect the consumer, but this approach has limitations in scenarios where pausing and resuming consumption is required without fully disconnecting.

#### Use Case
In our test suite, we need to:
1. Consume all existing messages from a topic.
2. Pause the consumer to produce new test messages.
3. Resume the consumer to consume only the newly produced messages.

Using `disconnect` as a workaround requires reinitializing the consumer and handling group rebalancing, which is both error-prone and inefficient. Similarly, `pause` and `resume` do not allow us to reconfigure the callback logic dynamically, as the `run` method cannot be called again after the consumer is already running.

#### Proposed Solution
- Allows pausing message consumption without fully disconnecting the consumer.
- Supports re-executing the run method to dynamically adjust the callback logic or reset the consumer's state.

#### Additional Context
- [Migration Guide](https://docs.confluent.io/kafka-clients/javascript/current/migration.html)
- Current workaround: Disconnecting and reconnecting the consumer.
- Using `pause` and `resume`, which does not allow re-executing the `run` method to adjust callback logic dynamically.

Thank you for considering this feature request!
