fix: add group/consumer to hash to avoid overwriting

[fbraem]

Description

This allows subscribers to use the same Redis stream:

• with the same group, but with multiple consumers to load balance the messages between several subscribers.

@broker.subscriber(stream="test-stream", group="test-group-1", consumer="test-consumer-1")
async def handle_1(msg: str):
    print(msg)

@broker.subscriber(stream="test-stream", group="test-group-1", consumer="test-consumer-2")
async def handle_2(msg: str):
    print(msg)

• with multiple groups to allow a message to be handled by multiple subscribers (pub/sub)

@broker.subscriber(stream="test-stream", group="test-group-1", consumer="test-consumer-1")
async def sub_1(msg: str):
    print(msg)

@broker.subscriber(stream="test-stream", group="test-group-2", consumer="test-consumer-2")
async def sub_2(msg: str):
    print(msg)

Without this fix, the subscribers are overwritten because the group and consumer are not part of the hash.
