Description

I'm implementing the iceberg-rust now and we use the avro-rust to write the manifest file. In iceberg spec, the uuid is the logical type of fixed rather than string as avro spec. So I need to customize the logical type using attributes of the schema.  But I find that in avro-rust, the attribute of schema will be ignore when serialize. Like: https://github.com/apache/avro/blob/28cdbd8f00ee16866bc7610aea2a878f7a0304dc/lang/rust/avro/src/schema.rs#L1890

I'm curious why they are ignored and would it be possible to support serializing them so that the user can custom their logical type?
