Hey @quentin-quix, it looks good overall, with only a few minor comments 👍

Question: How well does it work with more complex Protobuf types like Enums? E.g., Enum can be deserialized as enum.Enum and as an int.
Do we cover that?

Also, please remember to add the info about Protobuf to the docs (see docs/advanced/serialization.md).

There is an argument for it that we should expose, use_integers_for_enums.

I think new serdes classes need to be imported and added to SERIALIZERS and DESERIALIZERS maps in quixstreams.models.serializers.__init__

We don't want to do it for protobuf since it needs an extra import. Importing it in quixstreams.models.serializers.__init__ would raise an ImportError due to the possibly missing dependencies. We could catch the error and skip it but iirc we decided against it
