Hi, I am working on reading Avro from BigQuery Storage API, the response from BigQuery creates a raw Avro binary output, the `Reader` implementation doesn't work since it expects the header to be present, so I turned to use `from_avro_datum` interface, however it killed the performance of the app, upon inspecting this, it turned out that this happens because it's resolving the schema multiple times, see the flamegraph below, but basically `ResolvedSchema::try_from` is `80.26%` of the `from_avro_datum` call. Can we expose another interface for `from_avro_datum` that takes in the `ResolvedSchema` object instead? Or maybe better, create a binary deserializer, in Java this works by using `GenericDatumReader<>(schema)` and creating a decoder with `DecoderFactory.get().binaryDecoder` <img width="1791" height="695" alt="Image" src="https://github.com/user-attachments/assets/46fb6e65-2afd-4136-890f-e6c8a95cc668"; /> -- This is an automated message from the Apache Git Service.
