Loads a chunk from a file on disk or network.

Parameters

Filename	The full file path to the file.
OutLoadResult	Receives the result, indicating the error reason if return value is nullptr.

Returns: ptr to an allocated IChunkDataAccess holding the data, nullptr if failed to load.

Implements BuildPatchServices::IChunkDataSerialization.
