Support for Multi-Topic Consumer in DotPulsar

[savan-rangrej]

Is your feature request related to a problem? Please describe

Hello DotPulsar Team,

I am currently working with Apache Pulsar and using DotPulsar for my messaging needs. I have a requirement to consume messages from multiple topics with a single consumer. This is a feature available in the Pulsar Java client, and I would like to see similar functionality in DotPulsar.

Java Client Example
In the Pulsar Java client, I can subscribe to multiple topics using a pattern or a list of topic names, as shown below:

Pattern Example:

Pattern pattern = Pattern.compile("public/default/.*");
pulsarClient.newConsumer()
        .subscriptionName("my-sub")
        .topicsPattern(pattern)
        .subscriptionTopicsMode(RegexSubscriptionMode.AllTopics)
        .subscribe();

Multiple Topics Example:

Consumer multiTopicConsumer = consumerBuilder
        .topics( "topic-1",
        "topic-2",
        "topic-3")
        .subscribe();

I would like to request the implementation of similar functionality in DotPulsar. Specifically, the ability to:

1. Subscribe to multiple topics using a regex pattern.
2. Subscribe to multiple topics by providing a list of topic names.

These features would greatly enhance the flexibility and usability of DotPulsar for handling complex messaging scenarios.

Thank you for considering this feature request. I appreciate the hard work and dedication of the DotPulsar team.

Best regards,
Savankumar Rangrej

This seems to be a duplicate of #5. This feature would also be very useful in our case. Hope there will soon be some traction on it
