Add use_proto_names support for schema_registry_decode processor

[AlmogAlmado]

Hi Guys,

I've created this pull request to add support for the use_proto_names option in the schema_registry_decode functionality. This option allows users to specify whether to use proto names (true) or not (false) during decoding.

Could you please review and share your thoughts? Let me know if any further changes or information are needed.

Thanks for your attention.

Best regards,
