feat: add stream support for consumers

[l4mby]

This PR adds stream support for consumer, the consumer now can be declared as such:

const consumer = await connection.createConsumer({ 
  stream: { 
       name: "some-stream",       // mandatory
       offset: Offset.first(),            // optional
       filterValues: ["invoices", "orders"],  //optional
       matchUnfiltered: true         // optional
  },
  messageHandler: (context, msg) => /* ... */ })

We also added support for filterValues.
Note that if both offset and filterValues are not defined the client will throw an error, since to use message filtering at least one parameter is needed.
