Warn once for unmapped instance folders

Replace a hard error for unimplemented instance folder names with a warning that is emitted only once per unique folder name. Introduces a containers.Map (hasWarned) to track which folder names have already triggered the warning and uses the identifier 'OPENMINDS:InstanceLibrary:createInstanceTable:MissingTypeMapping'. This avoids aborting execution for unmapped folders while preventing repeated duplicate warnings.
