This leads to madness, as some formats are supersets of the detected types, e.g. 'intel-me' is detected as 'quad' and 'bcd' is detected as 'pair'. Where the version format is defined in a specification or hardcoded in the source use a hardcoded enum value, otherwise use a quirk override. Additionally, warn if the version does not match the defined version format
