Batch Patron Deletion (Trash) has a fairly long run/load time compared to Batch
Patron Deletion (Permanent). I have attempted to improve the runtime of the
Batch Patron Deletion (Trash) tool and my enhancement reduces the time to
modify a batch of patrons by an average of 78.21%

I discovered the extended runtime was mostly due to the overhead
DBIx::Class::ResultSet which I switched to basic SQL calls to the $dbh which
reduced the trashing of 1000 patrons from 24.84 seconds to 5.41 seconds, saving
19.43 seconds of resultset calls.
