DumpLogicalLog can dump transactions relevant to cc report
after a consisistency checker has run a report is made, potentially including incosistencies. DumpLogicalLog can be given a --ccfilter which should point to such a report file. DumpLogicalLog will then only include transactions which touches any of the records in the cc report and mark the records it matched with a `<----` arrow to easier navigate.
