Introduced a new FindFileCallback to Registry to compliement the existing ReadFileCallback and WriteFileCallback. Added support for assign Find, Read and WriteFileCallbacks to osdDB::Options to enable plugins/applications to override the callbacks just for that read/write call and any nested file operations
