I am using a native sort script & I wish to deserialize source inside it. I have access to the SourceLookup object.

`SourceLookup source = source();`

which gives me the bytes

`byte[] bytes = source.internalSourceRef().toBytes()`

What is the serialization format of this object's bytes and how can I deserialize it efficiently?
