* Better Reporting Fixes an odd issue where the design names extracted would be timestamps due to "File not found or empty" being printed and split, creating extra columns. Also makes the reports explicitly detail if the OpenLane flow has failed outright on a design. A general cleanup of relevant scripts has been performed. Fixes #495
