Getting a single binary-encoded object [OCFReader.ReadBinary() function?]

I'd like to be able to take an OCF as input, then pull out individual binary-encoded objects one at a time. I will store the schema separately and later apply it to these individual objects using Codec.NativeFromBinary.

I can currently use OCFReader.Scan/Read and Codec.BinaryFromNative to get a single binary-encoded object, but the call to OCFReader.Read invokes Codec.NativeFromBinary. Because performance is an important consideration in this, I'd like to be able to skip those redundant decoding/encoding calls.

Ideally, something like OCFReader.ReadBinary() would return a []byte containing exactly one Avro object. I'm trying to implement it, but being unfamiliar with goavro I'm having a hard time figuring out if I can generically pull out the slice of bytes representing a single object without basically reimplementing nativeFromBinary functions for each Avro type. Any suggestions?

Start by tracing OCFReader.Scan and Read alongside Codec.NativeFromBinary and Codec.BinaryFromNative to understand where individual object boundaries are available. The change is complete when an OCF reader can return each object as its original []byte without redundant native decoding and re-encoding, while preserving the existing read behavior.
