Delegate OrtModelCompilationOptions.GetInitializerLocationDelegate

Delegate called by ORT for every initializer when generating the compiled model. The delegate allows the user to determine whether the initializer should be stored within the compiled model or externally in a file. If the delegate chooses to store an initializer externally, the delegate implementation is responsible for writing the initializer data to a file.
