SeaPkg/test\_aux: Add offset and size columns to results table @makubacki (#533)

Change Details

Description

When given a failure like the following:

It is convenient to have the offset and size printed in the symbol result list. You can quickly verify the offset against other sources and confirm the size matches what is reported in the error.
