Add several new b-tagging tunings to b-jet trigger
We don't have the final tuning for b-jet trigger yet, but we have a number of improvements from offline training that might be an improvement in the trigger as well.
Some of these trainings used much looser track selections than we use in the trigger, so this should help us quantify any loss we get in performance due to trigger tracking. Tagging @cpollard for a look.
